Semi finals 

A contest/event where a bunch of guys get together to compare the length and girth of their semi's. The winner receives respect, as well as the envy of others present at the event.

Paul : "Dude, the semi finals are being held at Jeff's mom's house this month."
Josh : "Sweet, I'll bring some Red Bull, a tape measure, and some partial nudity shots of Sigourney Weaver!"
