the corn smells nice 

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?!"

The Corn Smells Nice 

A code word for describing someone's fetishization of taking a shit on another's chest.

Person A: Hey, did you know Emile thinks the corn smells nice?

Person B: Yo that's pretty fucked up, I didn't know he was into that sort of thing.

Person A: Well let's not kink shame over here, I still think he's cool.
