Does anyone remember this movie?

Question

I can't remember the movie title, but it was about an over weight kid that was working on some big science experiment for college. He also asked the pretty girl at school to the prom, but his nerdy friend leaked an embarrassing video of him. He wore a plum suit to the dance, and got the girl in the end.
