Burst a nurst

A phrase coined by Vinny, of Vinesauce, a corruption of the phrase "bust a nut", somewhat hyperbolic way of describing frustration, similar to claiming that one will have an aneurism, a conniption, or a brain haemorrhage when faced with a frustrating activity.
Would occur when in, for example, a platforming game, one is able to clear a small part of a section, but the final hurdle seems impassable, and failure causes one to restart from the beginning of said section.

This game is going to make me burst a nurst with this god damn jump.
I'm gonna burst a fuckin' nurst with this fight.

Nurst

When someone laughs really hard.

"i just burst nurst" "i just nurst out laughing" "im nurst" "im nursting" you can just say "nurst" by itself, too
