A synonym for the "red card" in soccer.
Reason: When they started to watch soccer on the TV, they couldn't tell the yellow cards from the red cards, because of the lack of color. So The referees started to keep the yellow card in the bag of their shirt and the red one in their trousers. So iteraly near their ass.
