a girl who flirts and leads on every guy and cant control herself. May not seem like a bad person, but FLIRTS WITH EVERY SINGLE GUY SHE KNOWS. She will instantly ditch you after a week, the longest, for her next victim. Friends who are girls dont exist, you destroyed them all.

Get the cock-a-tease mug.
Used by women to gain power and/or humilate male friends and colleagues by the art of making perfectly normal men turn in to delusional idiots when they think the cock teaser actually has been wanting sex with them.

The magnitude of the effect is directly proportional to the time spent being teased and/or your position within the organisation
"That bitch has lead me on for weeks! And I told her the plans for our management restructure!"
"What a cock teasing you've had!"

A title to describe (usually pretty) flirty girls used predominantly by horny and or desperate males who are too dumb to realize that at that she was never going to sleep with him.

1. A female who is usually significantly more attractive than the man she appears to be with that will flirt with him a lot and get him to spend a lot of money for the prospect of sex, and then abruptly fuck him over (in the figurative sense of course) by never talking to him again and/or dumping the shit out of him via the bulletproof lets be friends method.

Cock teases are typically thought to be the minions of a larger, more evil force.

A cocktease is a girl that makes a guy horny, but never goes further than that becuase she is:
A) A girl that knows that a good time does not have to end in your bed.
B) Somebody that is spontaneous and friendly to everybody causing weak guys to be under the false and desperate impression that she wants more than friendship.
Tom: wow this girl is so fucking HOT. She danced with me, kissed me on the cheek, shared a drink, even let me rub her back.

Tom: Hey baby want to go back to my place for coffee?

Girl: Fuck off creep!

Mike: What a cock tease!

Tom: Yah!
