IFHH
An acronym for "I fucking hate her." Slang tossed around by high school students when words can't describe the violence and hatred they feel towards the school slut, whore, bitch, etc. when they do something particularly disgusting, get a new STD, or make an attempt to get into your boyfriend's pants. There is no better form of revenge than to create an official IFHH group in your school.
