pissrection 

When a male recieves an erection from holding in his piss

I took a 7 hour car ride and didn't pee for the entire trip. I popped a fat pissrection and my whole family laughed.

pisdirection 

The tendency for piss to shoot in random directions when going to the bathroom right after having sex.

After the last bout of sex,I had to sit down to take a piss out of fear of pisdirection.
