I’ve long been aware that hand-gestures mean different things in different cultures. For example, in many Southern African tribal contexts, to see two male friends walking hand-in-hand is absolutely normal as a gesture of friendship and unity; but in the USA, it’s usually found only among gay couples. In the USA, to ‘give someone the finger‘ involves a single digit; but the equivalent gesture in the UK uses two, in a reversal of Churchill’s famous palm-outward ‘V-for-Victory‘ sign.
Now the Telegraph brings us a photo gallery of hand gestures that may seem innocuous to us, but mean nasty things in other cultures. For example:
Meaning: Are you an idiot?
Used in: Brazil
A South American gesture indicating stupidity, this requires improv skills and an actorly flair. To perform, put your fist to your forehead while making a comical overbite. The gesture is most effective when accented with multiple grunts. When executed correctly, you will be rewarded with appreciative laughs, though not, perhaps, from your subject.
Meaning: You’re stingy
Used in: Mexico, South America
Just as the heart is associated with love, so, in many Latin American countries, is the elbow with stinginess. In Mexico the two are so closely linked that a miser is described as “muy codo” (very elbow), the idea being that he rarely straightens it to pay the check. If your compadre makes a habit of failing to pick up the check, you may wish to correct his behaviour with this sharp gesture. For extra emphasis, bang your elbow on the table.
Note: In Austria and Germany the same gesture means “You’re an idiot,” suggesting that the elbow is where the subject keeps his brain.
