MCOW

Mystery Cock of the Week

A bonding ritual undertaken by fraternities in which a photograph of each member's penis is anonymously sent across a fraternity email list each week. The other frat brothers must then try to guess to whom the penis belongs.

Dude, is it gay that Delta Chi is starting a MCOW?

No, man. Its just brotherly love.

Grimace cried out "McOw!"
