When you take such a furious burning shit that when you're done, your asshole appears to be gasping for air like a guppy out of water.
After that pinch of Copenhagen and that cup of coffee this morning I had serious guppy butt. Musta been those hot wings last night.

Get the guppy buttmug. A butt guppy happens when you're finished taking a shit but your asshole won't close and is hanging open like a guppy gulping for air.
The other day my starfish squeezed out a girthy turd and it left me with a butt guppy. I think I might be getting ass flu and will have to go home scule.
