How do i get rid of her?

on friday i went to club as usual got drunk alone because my friends were crushing a party which i thought it was a bad idea. i hooked up with chic in the club danced together and got more drunk. on Saturday morning i found a friend request on facebook and she had been calling but i don't want to answer coz i cant remember ****. as far as i know she was just a chic i was ******* with. she is so ******* annoying.
