A special kind of guy who embodies awesomeness but can sometimes be a tough cookie. looks meh with glasses on but is confident enough to not give a fuck. Loves Manchester United. If he could marry it he would (no homo). Uber social with more friends than he can count. The only Egyptian guy I've ever come across who's a revolution pussy. Aims derogatory terms to ones he's sexually attracted to. Shows affection by calling them bitches which even if you tell him it annoys the shit out of you, to him it just goes unregistered. On rare occasions he'll say something sweet and when he does, he will surely melt your heart! But it's always short-lived. The most innocent little bunny ever! And the best online friend a girl can ever ask for.
Friend 1: omg who is that hottie over there? I like his swag!

Friend 1: give me a piece of that ass.
Friend 2: be careful with him or you'll get burned. He's highly flammable.
