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?!"
A sexual act where one feeds a woman corn every hour for an entire day. The following morning he shoves his cock in her ass and pulls it out. He then proceeds to have her eat the corn off his cock.
That Bitch kept complaining she was hungry so I gave the bitch the corn on the cob.
Nickname given to bales of marijuana thrown overboard or out of airplanes. Origin is reportedly from members of the US Coast Guard in the area of Southern Florida.
