When a man urinates and his piss goes into two split directions causing a great difficulty in control of keeping the two separate piss to go directly in the toilet. Usually ends up in a big yellow mess around the toilet and/or the floor.
This morning I was so mad because I had a Two Lane Way Piss which ended up with a big mess on the toilet and the floor!
