shitflap

The matting of poo and hair around the anus due to lack of proper wiping after a bowel movement.

Man drank so much beer last night that I woke up this morning and took a shit that gave me a huge shitflap!

shitflaps

The festering labia of unkempt female genatalia.

"Did you go down on her?"
"No, she had shitflaps didn't she?!"
