When a non-attractive person goes through puberty and becomes very attractive as a result.

First seen on Tumblr and Imgur, this term refers to Matthew Lewis's battle and victory over puberty.
"Have you seen Lisa since grade school?"
"No I have not, she really Neville Longbottomed. Damn."

"I was staying at my friend's house when her brother who I haven't seen in years walks in to say hello. I was in shock, as he Neville Longbottomed."
