I first saw this usage in a Sports Illustrated article about the baseball manager Lou Pinella. In the article Pinella, who is notoriously bad about arguing with umpires, referred to himself as a red ass. I liked the term so well, and it applied to some in my family, it was entered in to the family lexicon.
Anyone is free to catch it. If the person attempting to catch the ball bobbles it, they must run to touch
the wall before being pelted with the ball by another player.
If they are unsuccessful in reaching the wall, the player must stand, facing the wall, whilst each of the other
contestants throws the ball at his rear end.
Adj: That guy has the red ass.
