A guy who's creepy, and hugs or kisses inappropriately. He has a rapist lure. You don't think he would do it but definitely gives off that vibe. i.e. creepy hugger at the office.
Luisa: Ew, Al Just hugged me.
Maribeth: Ew, Gross.
Luisa: I know he's so rapey.
Maribeth: Yeah total Rapefest.
Someone who has a creepy, I-want-to-get-into-your-pants look. Their leer often turns into action, and before you know it they will tell you that it wasn't rape because you liked it.
Can be male or female, or undecided in the case of certain unmentionables.
Look at Captain Underpants over there, he looks quite rapey, you should probablystay away from him unless you are a nymphet.
