look up any word, like pussy:
 
1.
A word describing the small size of a man's penis. Usually those of Asian descent, since they can't say most beginnings of a word anyways.
Me - You totally kicked me in the penis Mr. Wang.

Mr Wang - Sorree about your reenus. I know its bigger than mine and robably hurt more. Sorree

Me - You are forgiven sir.
