Usually an emo with pointy (most often blonde, black, blue, green, ping or red) dyed hair. The not-so-rare specie of posefags usually puke to lose weight, they often use skinny jeans, have piercings and listens to lame deathcore. Their primary mating-sounds is pigsquealing.
PS. They're camwhores.
-"I bet he's an emo because of his lack of style."
-"Oh really? He looks more like a posefag in those skinny jeans."
-"Dude, is he a girl?"
-"Nah, he just poses like one!"
