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."
