comes from the geek word stavrou.
def: Little white penis sitting in the back of your CCNA class. He has a little mushroom head and ejaculates a milky white substance. He also likes to wear underpants on his head. Stavrou is a dangerous sex machine that has the ability to seduce any human being man or women.
Stavrou poked me in the butt last night!
Can I play with your Stavrou?
