In the popular film franchise Harry Potter , Neville longbottom goes from being a slightly geeky , chubby child to a fit as fuck adult. Similar to a glo up, if someone has Neville longbottomed they have gotten significantly hotter

One of Harry's fellow Gryffindor's - and a member of his class. His parents got tortured over and over again by a Death Eater using the Cruatious curse - until they permananently lost their minds.

A sad and lonely individual who hasn't lived up to their potential yet.

The transition for a (most likely make) actor from his dorky teen year to his hottness supreem prime. Like the actor that played nevil longbottom from the popular Harry Potter franchise, Matthew Lewis. Mathew was a cute chubby kid, but evolved into a very dorky teen, like one of those weird second forms of a new generation Pokémon. But low and behold, after the Harry Potter ended, he became so hot that most of us honestly couldn’t even recognize him as Neville anymore.
Example: Remember woody, from the suite life on deck? Yeah we’ll go look him up now, we’ve been nevil longbottomed again boys
