Balls of increasing size evenly spaced on a string that you tuck away in your (or your partner's) anus. Then, right when you're about to orgasm, and not a moment before, you gently pull the string thereby releasing the balls uno by uno. Benoit balls come in plastic and metal, from petite to gi-normous.

The nickname given to a hotel concierge named Benoit in "Jeu Monégasque," a season 2 episode of the FX show, "Archer."

Also: misspelling of Ben Wa Balls.
