The inability to aim your piss correctly whilst you have a boner.
I awoke in the middle of the night, half asleep, needing a piss. As I was doing my business I realised I had a boner it went in every direction possible other than towards its' intended target. I'm going to need to wipe it up in the morning....maybe! I must suffer from erectile pisfunction!
