a guy or girl who is just an overprotective scumbag when it comes to dating. It doesn't have to be a boyfriend/girlfriend. It could simply be someone who is arrogant, a jerk, a scumbag, or someone who has no regard to one's friendship/relationship
Boy: let's get coffee sometime, you are awesome to be with!!

Girl: uh.. I don;t know.. my boyfriend wouldn't like that

Boy: so over-protective!!!

Girl: yea

Boy: don't let that fucking roach tell you what to do!!!

Girl: don't worry... will do so

A very creepy guy. The kind of sleazy, dirty guy who is probably a druggie, likely has a criminal record, and shamelessly hits on anything with a vagina in the rudest way possible.
Creeper: Hey! You girls are looking fine. I could take all three of you in bed.
You: Ew, what a roach.
