It's a game that every kid and some adults knowingly and/or unknowingly play. If you don't clean up well after going number 2 you get skidmarks in your underwear. The person with the worst skidmarks in the house is the Skidmark Hero.
Child - Can you wash my clothes?
Mom - I don't mind washing your clothes. But, if you keep playing Skidmark Hero, your going to wash your own undies.
