A character (professor at Hogwarts) in the Harry Potter book series by J.K. Rowling (or, for you illiterate bastards, in the Harry Potter movies).

Characterized as a mean, slimy, suspicious and unpopular professor hated by most of the school's students, especially those outside of Slytherin.

This term can also be used by the hopeless Harry Potter geek to refer to said geek's least favorite teacher.
HP Geek #1: I can't belive Snape gave us so much math homework! I was going to finish chapter 54 of my Draco/Hermione fan fic!
HP Geek #2: I know! Wait, should I be concerned that I understand what the hell you're saying when you use Harry Potter words to refer to aspects of real life?
HP Geek #1: Probably. Maybe you should go see Madam Pomfrey in the hospital wing.
HP Geek #2: Doh!

is what many may call heroic, a daring, bold, brave, not-afraid-to-stand-up-to-the-Dark-Lord kind of person. Nowadays, we shorten it to badass.
Random person who just finished watching Deathly Hallows: Isn't Neville Longbottom just soo badass? He killed Nagini, Voldemort's horcrux!

Knowledgable person: Professor Severus Snape saved Harry's life several times and he played spy for Dumbledore. He's more badass than Neville Longbottom!
