This guy wants attention and likes making people wonder if he's a guy or not. Why else would he wear what he does and try to sing a girls song with those lyrics.
Believe it or not I think this guy is afraid of rejection.
I know that doesn't make sense but I would be willing to bet that the reason he dresses and acts that way is so if or when he is rejected then he can just blame it on the fact these people can't handle the way he looks which makes it their problem that he is rejected and not his.
The people that do want to be around him are gonna be people who are full of compassion and will make a point to accept him which is what he wants so I can't say that he is a dummy, just an odd ball that creeps me out a little.
