A homo-erotic sex event in which one man throws a party for ten of his friends in hopes that they will sexually abuse him. Usually associated with the liberal city of Seattle, Wa these events are often disguised as football parties so as to allow closeted members to participate. Hosts wishing to advertise the affair and increase attendance will often place a flag or banner outside their home or decal on their vehicle.
-Hey you guys want to get a beer?

-No thanks, Seattle is playing and we have an eleventh man (11th man) party to attend.

-You guys are gay... see you later!
