User_2006 is that whiny prissy prep. Dresses very sharp, even in his spare time, smiles extra hard for photos, works extra hours to study and most importantly knows someone in every other clique (whether they like it or not). He's a hard guy to hate, he's enthusiastic, hardworking and pitches in when it's a teamwork situation, the real issue comes when he feels he's underperforming.
He's the kind of guy who wants to be Phelps while he's still struggling with the breaststroke, so he focuses too hard on that and loses his skill at front crawl and butterfly as he fails to practise the muscles for them and loses all races as he stretches himself thin. You could also compare it to a geek who spends too much time obssessing over one particular hobby and interest, neglecting everything else about a subject so that even in the subject that it relates to, they score poorly overall.
We all know someone like this, even in the roughest schools there's always the tryhards, however the quinetessential aspect of this type is that they know they're a tryhard.
