To have a bath with a girl and have a turd in there. If the girl discovers that you have let one go in the bath you punch her.
i was having a romantic bath with my girl when suddenly a really needed a shit but i didn't want to ruin the moment i was having with her by saying so. so i tried to sly one out but she noticed so i lamped her one, she loved it.
She now loves San Antonio Steamers regularly and i try to suprise her every time.
