Neville up

To become ridiculously more attractive than one's former self, primarily, but not exclusively, as a result of puberty. A pun on 'level up', referencing the unexpected transformation of Neville Longbottom (Matthew Lewis).

"Did you see what that kid from ET looks like now?"

"Yeah bro, I didn't expect him to Neville up like that."

Nevilling up

When you go from an ugly duckling as a tween to an absolute stunner as an adult.

Matthew Lewis is the quintessential example of Nevilling up

Nevill Up

In the movie Harry Potter, Matthew Lewis plays the role of Neville Longbottom. Neville is the portrayal of growing up awkward, "unattractive', made fun of, etc. As an adult, Matthew Lewis is now considered to be rather attractive by many standards. As Nevill's experience is such an accurate representation of the "glow up" process it should said that Matthew Lewis...Nevilled Up.

You can...

1. Neville Up
2. Be Nevilling Up
3. Have Nevilled Up

Oh my gawd, is that Josh? Did Nevill Up or what!
