phenomenon that occurs when you fail to urinate (usually due to passing out from all the booze) after sex and before going to bed. the following morning you wake up with spare amounts of dried up jism in your piss tube. unsuspectingly, you go stand over the toilet. out come the piss and it parts like a snake's tongue, usually totally missing the bowl.
after picking up some girl from last night's bar trip, I woke up this morning with some serious split pee that went all over Lee's bathroom wall.
