stiff piss 

When a male attempts to urinate standing up while his penis is erect. In most cases he must squat, bend, etc. in efforts to get his penis as close as possible to the bowl without actually touching it leaving him in a peculiar and uncomfortable position. This normally occurs in conjunction with morning wood, or immediately after ejaculating.
