butt pressure

When you store in so much farts because of social norms that an intense sharp pain rises in your anus and rectum.

Ah man, I just had so many baked beans at this wedding and now my butt pressure is at a extremely high magnitude.

Pressure shit

When you have been holding in a shit for a little longer than expected and then, when you finally release it, it feels like 1000lbs of pressure has been released

Bro, I couldn’t shit during my last shift so when I got home I let out a massive pressure shit!

pressure flip

One of the most disgusting skateboarding tricks to have ever existed, where the skateboard rotates in the direction of an inward heel flip but only performed with the back foot.

Wow dude, I can't believe that little kid did a "pressure flip" in a game of SKATE. What a douche.
Bro see that fat girl right there? She looks like a total "pressure flip".

Dude, Nate Sherwood "pressure flipped" the fuck out of him.

splat pressure

Trying to hold it in as long as you can, right before ejaculation in hope to make a bigger splat shot with some pressure behind it so it comes out like popping a champagne bottle.

Man, she was laying down and the only way to tag her face was to build some serious splat pressure!
