Little bits of rolled up tissue paper that get caught in a ladies beef curtains after using the toilet. A fanny worm in the mouth is one of the most disturbing things that can happen. It will scar you for life.
I was muff diving and all of a sudden I got a huge fanny worm in my mouth. It made me puke all over her lady garden
