Pulling a Blast 

Raging in a Discord server, and leaving before the community has a chance to tell you how big of an idiot you are.

Man: Did you see that his holiness The_Immortal wanted to build the Hangar bay of the Starship Enterprise?
Woman: That's ridiculous, did you tell him to get lost?
Man: Nope, decided he'd be Pulling a Blast before we could scold him.

doing a blast 

When a bowel movement is so strong that fast moving, high-pressured fecal matter hits the water and some poop splashes back into your asshole.

"Fuck dude, I just did a blast in there"
"OMG Jennifer, I'm doing a blast in the bathroom right now please bring toilet paper"
