When you wake up or after sex when you try and take a piss and it goes in multiple directions

The multiple streams of urine that happens the next time a guy takes a wizz after ejaculating. Makes hitting the target nearly impossible. Sitting down is recommended.
DAMMIT!!! I just pissed on my feet, the toilet paper, and in the magazine rack, I should have sat down. You win this one multistream...
