According to Chuggaaconroy in the TheRunawayGuys LP of Pikmin (episode
13), possible slang for pooping on someone's chest.
More practically, an example of very specific slang terms that have little actual purpose as they are incredibly niche or raunchy, yet sound
like perfectly rational phrases (
like deflower either meaning losing a flower... or sex.)
I just went on a date with my fiance, and let's just
say the corn smells nice.
You could
say some perfectly reasonable phrase
like, I dunno, "the corn smells nice", and someone would tell you "OH MY GOD, DO YOU KNOW WHAT THAT MEANS?!"
