when you call your girl by your ex's name.
oh and i had to take a dump one time at my girls house and it hit me all of a sudden so i ran to the bathroom and dropped my pants and before i could sit down, i dropped a turd on her bathroom floor. and to make it worse, it wasnt just a normal dump, it was like one of those "beer" shits and it just plopped (sp?) there.
i dont think she ever found out, but there was definatley a spot there...
