Denerdified 

Getting transformed from a nerd/geek into a cooler person (skater, cheerleader, jock, etc.)

This dude used to wear the same too short pants and too small
hoodie every day. then all of a sudden, the next school year, he went skater. SO MUCH BETTER LOOKING, he was... DENERDIFIED(de=reversed, nerd=geek,fied=um. something.)
