"Thumbs Up" redirects here. For other uses, see Thumbs Up (disambiguation).

A thumbs-up or thumbs-down is a common hand gesture achieved by a closed fist held with the thumb extended upward or downward in approval or disapproval, respectively. These gestures have become metaphors in English: "The audience gave the movie the thumbs-up" means that the audience approved of the movie, regardless of whether the gesture was actually made.


The source of the gesture is obscure, but a number of origins have been proposed.

Opposable thumbs

Carleton S. Coon, having observed Barbary apes in Gibraltar using the gesture, hypothesised in the anthropological classic The Story of Man that it is a mutual celebration of having opposable thumbs.[1] Critics have suggested, however, that the apes may be simply imitating humans.

Ancient Rome

Main article: Pollice verso

The Latin phrase pollice verso is used in the context of gladiatorial combat for a hand gesture used by Ancient Roman crowds to pass judgment on a defeated gladiator. However, the precise type of gesture described by the phrase pollice verso and its meaning are unclear in the historical and literary record.[2][3][4]

In modern popular culture, it is assumed that "thumbs down" was the signal that a defeated gladiator should be condemned to death; "thumbs up", that he should be spared. The latter view was popularized by a widely reproduced painting by the 19th-century artist Jean-Léon Gérôme, whose Pollice Verso (usually known in English as "Thumbs Down") depicts a triumphant gladiator looking up into the stands for the verdict of the crowd.


Desmond Morris in Gestures: Their Origins and Distribution traces the practice back to a medieval custom used to seal business transactions. Over time, the mere sight of an upraised thumb came to symbolize harmony and kind feelings. For an example in the 17th century see the Diego Velasquez painting The Lunch /articles/The_Lunch_(Velázquez)

World War II

The gesture's popularization in America is generally attributed to the practices of World War II pilots, who used the thumbs up to communicate with ground crews prior to take-off. This custom may have originated with the China-based Flying Tigers, who were among the first American flyers involved in WWII. The appreciative Chinese would say ”挺好的“ ("ting hao de"), meaning "very good," and gesture with a thumbs up, which in Chinese means "you're number one." High officials in Chinese government see it as a sign of respect. Any person from China will recognize this numerical gesture, and it can be seen in movies and photos of the era, though this has not been verified in print by American Volunteer Group (AVG) pilots.

During WWII, pilots on US aircraft carriers adopted the thumbs up gesture to alert the deck crew that they were ready to go and that the wheel chocks could be removed.

The use of the specific term "thumbs up" to describe the gesture can be found on a series of postcards produced by the Exhibit Supply Company of Chicago, Illinois during WWII. These cards were designed to be mailed to soldiers overseas.

American GIs are reputed to have picked up on the thumb gesture and spread it throughout Europe as they marched toward Berlin."[5] Combat pilots in the US and around the world still use this gesture.

According to Luís da Câmara Cascudo,[6] Brazilians have adopted the "thumbs up" from watching American pilots based in northern Brazil during World War II.

International usage

"Thumbs up" traditionally translates as the foulest of gesticular insults in some Middle Eastern countries, especially in Iran — the most straightforward interpretation is "Up yours, pal!".[7] The sign has a similarly pejorative meaning in parts of West Africa, South America, Iran, and Sardinia, according to Roger E. Axtell's book Gestures: The Do's and Taboos of Body Language Around the World."[7]

In Iran, it is traditionally an obscene gesture, equivalent to the use of the middle finger in the Western world.

In Italy, Germany, France, Greece and Hungary, in the right context, it can simply indicate the number one. Generally, it is perceived as "Okay" or as a gesture indicating "Good luck".

In Russia and Finland, the meaning of this expression is "awesome", "good" or "well done". Another meaning in Finland is equivalent to "keeping fingers crossed".

In Australia, a thumbs-up is generally perceived as meaning "terrific". Prior to World War II, a thumb thrust upwards was used by Australians to gesture "up yours", but the thumb does not have a rude connotation in Australia today. Australian Sign Language also assigns this hand shape the meaning of "good".

In the United States, American Sign Language users use this hand shape to indicate the number ten (10) when wiggled modestly left and right.[8] When held stationary and thrust toward another person the meaning is "yourself".[9] When lifted up by the other palm, the meaning is "help".[10]

In Japanese sign language, the thumbs-up indicates a man, or male gender as opposed to an extended pinky indicating female.

In India, although the gesture is well accepted, similar gestures have negative connotations:

  • While doing a thumbs up, if the hand is wagged from side to side in a reverse-pendulum like movement, it means "won't work" or "disagree".
  • Still, the acceptability of the "thumbs up" gesture is seen in the popular soda Thums Up.

In Egypt, Iraq and Israel, it means perfect or very good. It is widely common between people.

In Brazil, it can be used in lieu of saying "thanks".

In Denmark, thumbs-up generally means "awesome", or "good to go". However thumbs-down is usually perceived very negatively.

On the internet, and most particularly at the Facebook social media site, the thumbs up gesture is shown as an icon and is associated with the term "like" -- which within that context means to follow or subscribe to the page, posts, or profile of another individual or company.

Context-specific usage

More recently, these gestures are associated with movie reviews, having been popularized by critics Gene Siskel and Roger Ebert on their televised review show Siskel & Ebert — the thumb up meaning a positive opinion of a film; the thumb down meaning a negative one. The trademarked phrase “two thumbs up”, originally meaning a positive review from both reviewers, has come to be used as an indication of very high quality or unanimity of praise.

By extension from the movie review usage, many websites allow users to approve or disapprove of items, such as comments in a forum, products in a store, or even other people's reviews of movies, books, products, etc., by choosing to click either a thumbs-up or thumbs-down button. In the aggregate, this serves as an evaluation system. Other users may then see the total number of thumbs up and thumbs down given to an item, or may simply see the number which is produced by subtracting thumbs down from thumbs up. (In the latter case, an item which has received exactly ten of each would read as having a rating of zero, rather than one of +10/-10.) Often, users may view a list of items in order of popularity, as ranked by this metric.

Hitchhikers in the West traditionally use a thumbs up gesture to solicit rides from oncoming vehicles, although in this presentation the arm is generally outstretched with the palm and closed fingers facing the motorist. The gesture is also usually performed with the hand nearest the motorist.

In scuba diving, the thumbs-up gesture is a specific diving signal given underwater, in which the diver indicates that he or she is about to stop his or her dive and ascend. This occasionally causes confusion in new divers, who might automatically gesture thumbs-up when trying to indicate approval — actually indicating a desire to stop diving and to ascend.

In basketball, when a held ball occurs, an official will jerk both thumbs in the air, signalling that a jump ball is in order.

The Indian cola brand Thums Up, now owned by The Coca-Cola Company is named after this symbol, and uses it as its logo.
