The first two aren't really reasons they just bother me.
1. They wear skinny jeans which make their legs look like chicken legs (O_e)
2. They simply HAVE to have a frikken fringe covering their eye. WTF!?!
3. You see pictures of them on the internet kissing and/or making out with other guys. I mean, seriously. Come on! You are telling me they're actually straight? 
4. Some gays act pretty girly as I've discovered through the wonders of youtube. 
I can totally say they are soo not gay!
This does not apply to all so called "emo" boys.
