I had a friend that took a girl home from the bar one night. He said they got home and he went downstairs to get a drink while she was in his bedroom.
Later, as they were going about their business, he said he became paranoid that he smelled bad because he kept getting wiffs of porta-potty-esque stench, and he was worried it was him and that he was about to ruin it right in the middle of the action.
She left the premises the next morning without waking him. He said that he got up and showered and then went to his closet to grab a shirt, only to discover that the chick had ruined his closet floor. Apparently she had to go, but decided the closet was the best place, and thought she could get away with it since it was a random bar encounter that lead to the slumber party.
Little did she know, another of our friends knew exactly who she was due to a distant acquaintance. My friend got her number, called her, and asked why she shit on his closet floor. She denied it, tried telling my friend that someone else had come home with them the night before and had left in the middle of the night. My friend called her bullshit and told her to come back and clean up.
She showed up an hour later with cleaning supplies, and offered to pay for professional cleaning as well if he wouldn't tell anyone about it.
He did not take the second half of that deal.
