The opposite of a come on, a get off is a series of social cues and body language used to discourage an unattractive or otherwise undesirable suitor. Get offs are typically used by young females in clubs and may include activities such as clustering in large groups to avoid detection, hugging or otherwise feigning interest in friends (or, in
desperate situations, complete strangers who seem
friendly), disappearing off to the toilets for very long periods of
time, talking loudly about old boyfriends, studiously avoiding eye contact and, as a last resort, telling said suitor to fuck off. These signals may be misinterpetted by a particularly verenthusiastic or idiotc suitor, at which point the ancient technique of the bitch
slap comes into
play.
Variants include geddoff, getoff and getafuckoff.
Guy1: Did you
see that? Dude, she is so
giving me the come on.
Guy2: What, by giving you the
finger?
Guy1: I guess that's a get off, then.
