(n)

A forgetful, goofy wizard who became rebellious and bad-ass (see BAMF). A fellow Gryffindor in Harry's year (see Harry Potter), Neville used to be shy, friendless, tearful, forgetful, and a bit of a loser.
However, in Harry Potter and the Deathly Hallows, Neville became one of the most BAMFW (Bad Ass Mother Fucker Wizards) in the world. :)
B.A.M.F. moments of Neville Longbottom, in "Deathly Hallows":

1. He killed Nagini, Voldemort's snake, with the Gryffindor sword, whilst his head was on fire.
2. He stood up to Voldemort, saying boldly he wouldn't join them until 'Hell freezes over'.

3. He stood up to the Carrows, asking them how much Muggle blood they've got.
4. He kept recruiting Dumbledore's Army even after Harry, Ron and Hermione had left.
