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.
