What my friend (who LOVES Harry Potter) did to a guy who insulted Harry Potter-

Guy: Harry Potter sucks.

Friend: *slams him into wall*

Guy: O_O

Friend: APOLOGIZE OR I WILL SEND A THOUSAND DEMENTORS HERE AND HAVE THEM SUCK OUT YOUR SOUL AND DO THE DEMENTOR'S KISS ON YOU!!

Guy: *stuttering* A-apologize?! T-to who?

Friend: APOLOGIZE YO HARRY POTTER!!

Guy: I-I-I'm sorry?

Friend: *releases him* Good.
