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?!"
