A crazy girl is just a girl that likes a guy that doesn't like her back; usually because said guy had sex with her and now can't believe she has the audacity to like him. She's acting like you have to LIKE someone to let them inside you. Ugh. Women
A crazy guy is just a guy that likes a girl that doesn't like him; usually because he saw her somewhere from a distance or talked to her briefly and perceived a signal that probably wasn't there. He writes her unwanted poetry and likes all her Facebook pictures going back years.
A crazy white boy is just a white boy who's crazy enough not to be nervous around black people. Black people are so accustomed to white people nervousness, a lack of nervousness is perceived as "crazy". I think it might also mean "isn't this crazy white boy? That you're a white boy and I like you?"
Now, there are genuinely crazy girls, guys, and white boys, but in general the above is what "crazy" means.
ACTUAL crazy girls do things like poke holes in condoms, show up at a man's place of business, stalk and throw public tantrums seemingly out of the blue. Can also be physically abusive, suicidal, or homicidal; mostly toward their own babies.
ACTUAL crazy guys run countries, corporations, bring guns to school, and rape women. Can be physically abusive, suicidal, or homicidal; mostly toward women or children.
ACTUAL crazy white boys are serial killers
Now, to be fair ACTUAL crazy women can do anything ACTUAL crazy men can do. I call these woman feminist heroes. I'm not saying I LIKE female rapists, but it is inspiring to see a woman break in to a male dominated field
Anyway, the point is, maybe it's time to tone down the crazy talk a little. It's getting a little crazy.
NOTE: All of this is based on my OWN experience; including the part that involves being shitty toward "crazy girls". I in no way think I'm better than any "crazy guy" out there. I have been one of you several times.
