Thumb Signal
A thumb signal, usually described as a thumbs-up or thumbs-down, is a common hand gesture achieved by a closed fist held with the thumb extended upward or downward, respectively. The thumbs-up gesture is associated with positivity, approval, achievement, satisfaction and solidarity, while the thumbs-down gesture is associated with concern, disapproval, dissatisfaction, rejection and failure. History Ancient Rome 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. While it is clear that the thumb was involved, the precise type of gesture described by the phrase ''pollice verso'' and its meaning are unclear in the historical and literary record.

Hand
A hand is a prehensile, multi-fingered appendage located at the end of the forearm or forelimb of primates such as humans, chimpanzees, monkeys, and lemurs. A few other vertebrates such as the Koala#Characteristics, koala (which has two thumb#Opposition and apposition, opposable thumbs on each "hand" and fingerprints extremely similar to human fingerprints) are often described as having "hands" instead of paws on their front limbs. The raccoon is usually described as having "hands" though opposable thumbs are lacking. Some evolutionary anatomists use the term ''hand'' to refer to the appendage of digits on the forelimb more generally—for example, in the context of whether the three Digit (anatomy), digits of the bird hand involved the same Homology (biology), homologous loss of two digits as in the dinosaur hand. The human hand usually has five digits: Finger numbering#Four-finger system, four fingers plus one thumb; however, these are often referred to collectively as Finger ...

The Lunch (Velázquez)
''The Lunch'' is a very early painting by Spanish artist Diego Velázquez, finished c. 1617. The work, an oil painting on canvas, is in the Hermitage Museum of Saint Petersburg. The painting portrays a table covered by a creased cloth, on which lie two pomegranates and a piece of bread. People attending the lunch include an aged man on the left and a young man on the right, while, in the background, an apparently carefree boy pours wine into a jug. The smiling man on the right appears to be ordering something, using Continental finger-counting. On the wall in the background hang a white neck-band, a leather bag and, on the right, a sword. ''The Lunch'' is nearly identical to another painting by Velázquez, '' The Farmers' Lunch'' (1618). The painting was on public display as 'The Breakfast' from February 2 to August 25, 2019 at the H'ART Museum in Amsterdam, the Netherlands, as part of the 'De Schatkamer!' exhibition.

Okay
''OK'' (), with spelling variations including ''okay'', ''okeh'', ''O.K.'' and many others, is an English word (originating in American English) denoting approval, acceptance, agreement, assent, acknowledgment, or a sign of indifference. ''OK'' is frequently used as a loanword in other languages. It has been described as the most frequently spoken or written word on the planet. The origin of ''OK'' is disputed; however, most modern reference works hold that it originated around Boston as part of a fad in the late 1830s of abbreviating misspellings; that it is an initialism of "oll korrect" as a misspelling of "all correct". This origin was first described by linguist Allen Walker Read in the 1960s. As an adjective, ''OK'' principally means "adequate" or "acceptable" as a contrast to "bad" ("The boss approved this, so it is OK to send out"); it can also mean "mediocre" when used in contrast with "good" ("The french fries were great, but the burger was just OK").
