1.) A girl who flirts with boys but has no intention of hooking up with them. Often giving them the impression that she has interest, but this will usually lead into a trap, or essentially "tricking" the boy into developing feelings for the girl. And in turn the boy will be stunned when he is rejected. Girls who do this are typically whores, and/or starved for attention. AVOID AT ALL COST!
2.) A girl who dresses provocatively, often focusing on her breasts, or ass as highlighted features to help draw attention of males. She uses this to arrouse boys at her disposal if successful. Hence the term "Cockteaser". On a sidenote: these girls will tend to act innocent as if they didn't know what they were doing, or what is going on. If a cocktease should ever give you the line "Well you read too much into it." SIMPLY RESPOND: "NO SHIT COCKTEASE, YOU GAVE OUT ALL THE SIGNALS YOU FUCKING WHORE!" OR "JESUS, YOUR SUCH A FUCKING COCKTEASE!"
Hannah talks to Eric and gives him several hints that she likes him. Some are subtle, but most are obvious. Over the course of time he will develope a friendship with the cocktease, and eventually ask her out on a date. When this happens she will either flat-out reject him or give him some lame brain excuse. When in reality, Hannah is fucking black guys in mall-parking lots left & right and God knows where else. Hannah is liar/cunt/whore...but above all, A COCKTEASE!
