Purge

From Cths

Purge is a somewhat crude and colloquial name given to the various kinds of bodily waste produced by Cybertronians. Though most commonly used to refer to something similar to vomit, it can also refer to other... kinds of waste products as well, though people usually like to use bilge in those cases, as it's also considered a bit more offensive, but the most profane word to use is bunk, probably short for "bunkum". "Purging" is how someone gets rid of purge, but the other variants can also be used as verbs.
