Nutpiss

When you take a piss after masturbating and your jizz is blocking the urinary tract, so it takes a bit more effort to peepee

"Alex always takes so long In the bathroom after we have sex. I think he's been having nutpiss"

Poopsuck

When your asshole sucks air in and causes pressure between your shit and the walls of your asshole

"Damnit jerry what took you so long? That was a 15 minute bathroom break"

"Sorry boss! I was constipated so I had to poopsuck in the bathroom"
