an emo scene boy is a exactly as it sounds. it is often used in terms of when people are acting melodramatic and bitchy.
"i am so pissed that we couldn't get those good seats, i feel like crying and not talking!"
"...stop being an emo scene boy!"
this is something guys say just to lead you on. They don't really want to. They just say it. Sometimes not even to get into your jeans, it's often used just to be nice, even though they really don't want to hang out with you. So remember this the next time some random, or even a guy you know, says this.
Guy: Yep, Im goin to the game tonight.
You: Thats cool, I might show too.
-----------few minute silence--------
Guy: Uh, we should hang out sometime.
You: Sorry! i know what you mean when you say that, thanks to urbandictionary.com
