My g/f was being a cunt one day so i told her i was gonna pepper her tampons when she went to work. She started being nice pretty quick. I have all kinds of good ideas
fart (unfiltered) on her pillow.. so when she wakes up.. PINK EYE BIATCH!!
or doo-doo under her door handles of her car.. that is if she has a car.. or do the poo dollar trick and leave it in her room with the poo-side down so she doesnt see..
