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.
Random Co-Worker: "So whats going on with you and Stacy?"
Stupid Sucker: "I spent 50 bucks on that cock tease and she won't even return my calls."

Evil whore who flirts with you a lot and manages to fleece you like a sheep for everything you are worth in a false anticipation that you will gain mindblowing sex in exchange for what you do. Well, the end result is that she gets what she ants and you get fucked in the figurative sense and must go back to the old threesome of me, myself, and I.
That girl is such a cocktease. I gave her a gold necklace and she took my heart. THAT BITCH!!!!!!!!
