A sexual act where 2 men hit their penises together.
I was in the bathroom when someone came up to me and asked me if I wanted to cross swords. He then started to swing his penis at me. That's not koo I said, so to defend myself, I swung my penis back at his. He took much pleasure in crossing swords.
