Eric was about to go down on Jessica when he noticed all of the blisters and scabs covering her vulva. He puked in his mouth a little and decided not to pull a herpes fuck on her, she had a scabby snatch and he didn't want to catch whatever it was she had.
An invented term for any nonspecific body part when one doesn't know the real name. Generally used to help describe vague illness or discomfort, as a placeholder until the actual name is learned, or in jest. The word was originally used on the cartoon "Muppet Babies" to describe a torture device, but came into usage as a generic anatomical term because it sounds so authentically biological.
Shit, I have a belly ache--I think my scrabula is swollen.
Keith went to the doctor because he fell off of his skateboard and broke his scrabula or some shit.
Person 1: "The New Human Anatomy." Huh. What about that book do you think is "new," man?
Person 2: Maybe it contains the human scrabula this time.
