Chronically Rebounded-On Girl 

A girl every guy goes to right after the end of his relationship. She is led on to think she has a chance of dating said guy. She is usually sweet and will fall for it every time. The guys usually never talk to her after they've been satisfied with their rebound time. Rarely ever has a boyfriend.

Ex.

Girl 1: I heard Emma went on dates with a bunch of guys, but never saw them again.

Girl 2: Really? She must be a chronically rebounded-on girl.

Mutual-Rebound-Sex 

The phenomenon in which two acquaintances/friends, both recently single after the dissolution of a long term relationship, become engaged in a purely sexual relationship. This must occur very shortly after the dissolution of said long term relationship.

This phenomenon is quintessentially mutual and void of strategic action and time ordering of events beyond the fact that both of your past relationships ended around the same time. Put bluntly, you both become single and then bam, one night you just start to hook up.

Person 1: It was really strange. Last night I thought I heard Adam leaving Jen's room.

Person 2: Ya that's kinda weird. They both just broke up with their ex's a couple weeks ago

Person 1: I think we're witnessing the MRS phenomenon

Person 2: Huh?

Person 1: Mutual-rebound-sex

rebound guy 

A guy who thinks he's gotten lucky since an attractive girl with a low self esteem decides to be with him. In reality, the girl is only dating him because she's trying get over another guy (A.K.A. she's "on the rebound"). The opposite/converse of this would be a rebound chick.

Cynical Friend 1: What the hell does she see in him? She's way out of his league.
Cynical Friend 2: Oh, it's nothing serious. She's just trying to get over her last breakup. To her, he's just a disposable rebound guy.

rebound sex 

the sex that helps someone to recover mentally from failed love affairs.

Example ( The Big Bang Theory S01E03):

Penny: I'm still getting over this break-up with Kurt.
And this thing with Doug would just be rebound sex.
...
It's just -- It's my pattern: I break up, then I find some cute guy

and then it's just 36 meaningless hours of ... well, you know
