left hook

this term can be used to define either one of two concepts: a) in boxing, a hard, sharp, diagonal punch to your opponent's left side of the face with your left hand, when you are facing them, regardless of whether you yourself are actually right or left handed. b) when 3 total strangers, a male and two females, sit in a row at a public place such a park bench or a city bus, the male sitting in between the two women, and the guy randomly decides to hook up with the woman sitting to his left.
