Gruntosaurus Rex 

taking a dinosaur-sized crap; would win the "shit of the year" contest; the kind of dump where you lose weight.

After not crapping for a week, I sat down and loaded up the bowl with a Gruntosaurus Rex.

Grunyon 

The Grunyon is a mythical late-night after-party spot located somewhere in Chicago, Il. Only reachable in the extreme stages of a hard brownout or blackout stupor, patrons of the Grunyon are hard-pressed to recall concrete details, but always report continued heavy drinking, cigarettes and Mexican food.

Q: What happened to you last night after the bar closed? We all left and you disappeared?

A: I went to the Grunyon.
