dormwrecker 

A person who sleeps with several people from the same social circle/group of friends, often within a relatively short period of time, thereby causing extreme awkwardness and tension at every social gathering they attend. This usually results in the dormwrecker being banished from the social circle; but, in extreme cases, may result in the disbanding of the entire group of friends.

Commonly occurring in dorms and college campuses, a dormwrecker may be seen as a nascent form of the homewrecker.

Wait, you hooked up with Suzie too?! That makes, you, me, Brian, Joe, Steve, etc...why does your girlfriend keep inviting that whore dormwrecker to all our parties?

Dormwreaker

Similar to a homewreaker, it describes a person who frequently stresses or destroys relationships in undergraduate universities by engaging one or more members of the relationship in conduct unsuited for traditional monogymous college dating.

"So I heard Becky was hanging out with Nick the other day on his futon and they were getting pretty cozy."

"Seriously? Nick is dating Becky's best friend. What a dormwreaker."
