It's sexual tension. There was this gay guy at my school who'd always mess with one of my friends. He'd like take pictures of him when my friend wasn't watching, and then have other people give him the pics wtf. After like a month of this I saw him crying, so me and a couple other buddies asked him what was up. Apparently the gay guy (who's actually really smart and nice) was telling people my friend was gay.
So we picked him up and walked him to the dean's office since he was too embarrased to go alone lol. FRIENDS FTW
Anyway we found out that the gay guy was just upset that my friend made some dumb comments to him. Nothing homophobic, but basically he said "sorry, I don't suck dick"
