Anal Irritation

The term used to describe the itching of the anus at night, due to threadworms. Whilst sleeping your body automatically scratches the irritation but it only gets eggs under your nails to produce more thread worms and gives you a nasty smelling hand.

"Dude, I have a proper bad case of anal irritation. I need to get checked out."
