When you poop and its not hard but not soft and its in the middle and its sticky.
Damn dude! That black dude left anal boogers all over the toilet.

A piece of poop inside the anus that has not seen light so it turns green like a booger when it finally is dislodged.
I had been feeling constipated for the past few days. I had a few big anal boogers.
