When a guy or girl breaks up with a boyfriend or girlfriend, then will go back to a ex-boyfriend or ex-girlfriend then break up with them and then hop to another ex. It also could apply to hopping between multiple ex's in a very short period of time.
Matt: Hey did you hear that Andrea broke up with her boyfriend?

Andy: Really.

Matt: Yeah and now she is got back with her Rick.

Andy: What a Ex-Hopper.
