Term used for a hot fart bubble that was held in for further fermentation to increase smell. Once released from the colon
oven those around you smell what you have been
cooking, which
may also include fecal matter.
"I need to get outta here, I have a buttbiscuit brewing and I
don't need to release it in this elevator"
"Ah dude, were you
cooking that buttbiscuit a little
extra, it smells like you shit yourself"
