Right you are Justin.
Definition: From Rondo Talbot's New World Dictionary.
"Monkey butt," mon-kee butt, adj., poss. descr. noun. A condition wherein a person has been riding dirt bikes so long, his butt starts to look like the monkeys and baboons in the zoo. coloration is often reddish or purple and the area looks inflamed. The condition is self-induced and is improved with a few days abstention from the activity of dirt bike riding. No other known cure exists for the malady. If you substitute the word "dirt" for "street," I am sure the great majority of us have experienced it. [smiley=embarassed.gif]
