Uncomfortable is an understatement. Being smart/geeky is their identity, the "self" that they see within, and it is something that separated them from the jocks. Seeing someone who looks like a jock but is smart/geeky must be like a punch in the face. The thing that made them who they are, the thing that they were made fun of and bullied so much for, is now so casually adopted by the people who did the bullying. It is similar to the feeling when male gamers see female gamers who portray themselves as geeky gamers or whatever after for years making fun of those geeky virgins and their video games.
