A form of male bonding. When two males share a urinal or toilet bowl during urination, the two males cross their pee streams in a manner to harken to the act of crossing swords in battle. They may even have pee fights where they trade stream hits much like jedi trade lightsaber blows.
In an act of brotherly bonding, Mike and Joe decided to cross swords one day.
