Pootential

Feeling as though you could poop if you forced it but it is not a full blown turd yet, more like a pebble or a small nugget.

" Hey man, there isn't a restroom for another hour do you wanna use the one at this gas station?

" Nah dude, I can wait an hour - I can feel there's some pootential here but I'd rather savour it for a decent poop"
