g-turd - A small poop that comes after you think you're done, like yo

A small poop that comes after you think you're done, like your poop is giving you the middle finger.

I was about to leave the bathroom, and then I got a g-turd like my poop was telling me to stay.

I thought I was done, but then I got a g-turd like my poop was giving me a finger.

After I finished my business, I got a g-turd like my poop was mocking me.
