The Neville Effect

The phenomenon whereby an awkward, unattractive, often pudgy-looking child grows up to be unbelievably hot.
The first observed case of The Neville Effect, and therefore the boy after whom the effect is named, Neville Longbottom (from the extraordinary Harry Potter series) is the typical example of this phenomenon. He looks a bit awkward and chubby when he is younger, but in a miraculous series of events, grows up to become a badass sex god. Other notable cases include Josh from Drake and Josh.

Neville Longbottomed 

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."

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."

Neville Longbottom 

To get significantly more attractive after going through the process of puberty.

Origin stems from Harry Potter, where the character Neville Longbottom (actor: Matthew Lewis) went from a dumpling shaped (but very sweet) 11 year-old to a daaaamn fine (and still very sweet) 25 year-old today.

The word was popularised by tumblr usage as both a noun and a verb.
Me looking in the mirror: I'd better Neville Longbottom by the time I get to uni, or I'm going to die alone. :/
Person returning home from uni: Is that...? Is that Susan?! Well she certainly Neville Longbottomed.
Person referring to their boyfriend: Nah, I'm not gonna break up with him. Yeah he's kinda pudgy, bit fingers crossed he'll do a Neville Longbottom!

neville longbottom 

BAMF.
Neville surprised us in the seventh Harry Potter by being such a badass. We now like to refer to him as BAMF. If he lets us.
Shall we review?

"Harry heard a scuffle and a shout, then another bang, a flash of light and a grunt of pain; he opened his eyes an infinitesimal ammount. Someone had broken free of the crowd and charged at Voldemort."
This badass would be Neville.

"The longer Harry looked at Neville, the worse he appeared: one of his eyes was swollen, yellow and purple, there were gouge marks on his face, and his general air of unkemptness suggested that he had been living rough. Nevertheless, his battered visage shone with happiness as he let go of Hermione and said again, 'I knew you'd come! Kept telling Seamus it was a matter of time!'
'Neville what happened to you?'
'What? this?' Neville dismissed his injuries with a shake of the head. 'This is nothing.'"

Finally the most BAMF moment of all:
"In one swift, fluid motion Neville broke free of the Body-Bind Curse upon him; the flaming Hat fell off him and he drew from its depths something silver, with a glittering, rubied handle-
The slash of the silver blade could not be heard over the roar of the oncoming crowd, or the sounds of the clashing giants, or of the stampeding centaurs, and yet it seemed to draw every eye. With a single stroke, Neville sliced off the great snake's head, which spun high into the air, gleaming in the light flooding from the Entrance Hall, and Voldemort's mouth was open in a scream of fury that nobody could hear, and the snakes body thudded to the ground at his feet-"
BAMF!
"If you're looking for Neville on the Marauder's map, he's labeled 'BAMF.'"

"Neville uses Nagini's blood as soy sauce."

"Neville Longbottom is what's beyond the veil."
