To Start Some Shiz?

Ok check this out...

I have this friend who is a girl. And she just got a b/f this past weekend.
He puts on her myspace comment...
"bogus dudes need to stop creepin on my girl..
i miss you<3"

which is cool, and to make a joke i said "and im the bogusest of them all" and she IMs me laughing at the stupidity that i am

well for some reason, guys have to be like this and he replies...

"no..youre just a douch bag..
cut your hair" - by the way I have long ass hair, and i've gone to cut it but everyone wont let me


So why do guys have to be dickheads like this? Jealousy maybe? I'm sure he has read our flirty comments from other times and is threaten but come on...
