Shit Pops

Sometimes I see/read the phrase "shit pops" and I think "what the fuck? Is that supposed to be like, a breakfast cereal?"

But just today I found myself saying "Shit, pops - you wouldn't catch me out with that weak-ass trick!"

I wonder if that's what people mean by that? And all along I thought it was just a real dumb phrase that didn't really mean anything. The difference a comma can make.

Hell.
