Yeah. The girl's a slut and fag's an asshole. You need to get him back for the eyebrow, so play it cool. Then lopp off his dick. In your mind. Then in reality, one night when he's passed out, shave off his eyebrow. If you don't want to be his friend anymore you could like shove his face into the ground and sit on his back and make him stay still while you shave off his eyebrow.

I'd probably rough him up a little at the very least, just so he knows never to fuck with you again when you pass out.
