Yes, it is a game played in college frat parties but has nothing to do with actual jousting. It is the act of two male parteners who are clearly intoxicated partaking in the act of sword fighting (this is where the jousting comes from) with their wangs on a bed (mattress).
It is commonly used as a joke to people who are clearly uninformed about the slang term.
