fartcatcher

An obsequious servant, waiter, or sales assistant; one who continually follows closely behind their employer/customer, fawning and pathetically eager to please.

High-waisted panties, specially those so high-waisted as to cover the bellybutton at the front, and look even more weird as shit for our sober modern standards from the back, as if the wearer had a great problem letting even the smallest amount of fart to ever leave her, hence the name.
