while i think there are girls who are classless enough to call men a lot of things for not buying them a drink, i feel like "sexist" is not likely to be on the list, esp not often enough to be listed under "when a girl tells me.." cuz that implies its more than once.
A black girl asked me for her lunch every day of freshman year. Not to share, the whole thing. Money too. I refused, and she called me racist. Every time. Then whenever she saw me in the halls she yelled out "RACIIIIIIST!!!! THAT DUDE IS SO RACIST!!!!"
Once a fat black girl was trying to bully me and then she once called me retarded because I was derping around in PE and then I called her ass retarded.
does that count?
