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.
