2. “ I love you ” sign.  Made using a combination of the letters 'I', 'L', and 'Y' from American Sign Language.  It is made by extending the thumb, index finger, and little finger while the middle and ring finger touch the palm. This is also the symbol used to curse someone in Italian culture.

3. Facepalm  This gesture indicates stupidity, usually a minor and immediately recognized slip of logic, judgment, or speech; and is performed by striking the forehead with the heel of the hand. Performed without the strike by simply covering the face with a hand, it means self-shame or bad memory (something forgotten).

4. Wave  A wave is a gesture in which the hand is raised and moved back and forth, as a greeting or sign of departure. The gesture can be used to attract attention at a distance. Most commonly, though, the gesture means simply "hello" or "goodbye".

5. Choking sign  The standard gesture to indicate that one is choking is to hold the throat with one or both hands as if strangling oneself. This is recognized as a request for immediate first aid for choking. It is promoted as a way to prevent onlookers from confusing the victim's distress with some other problem, such as a heart attack, when the person cannot speak. The gesture is sometimes used metaphorically to refer to someone or something "choking" in the slang sense of failing at something while under pressure.

6. Guns Up  Guns up is the slogan and hand signal of Texas Tech University.  It is used by students and alumni as a greeting. It is also used as a victory sign during athletic events.

7. Thumbs up  A thumbs up or thumbs down is a common gesture represented by a closed fist held with the thumb extended upward or downward in approval or disapproval respectively.  These gestures have become metaphors in English: "My boss gave my proposal the thumbs- up" means that the boss approved the proposal, regardless of whether the gesture was made — indeed, the gesture itself is unlikely in a formal business setting.
