toggle whop
A form of female masturbation using both a toggle and a whop. Similar to playing the piano, the index and middle fingers are used to stimulate, or toggle, the vagina. Then, the woman's hand is shaped to resemble a platypus bill as it firmly bangs the clitoris, like a beaver's tail, during climax. This expression is primarily used by gay men who are unfamiliar with vaginal pleasure.
I was outside on the fire escape smoking a Parliament and totally saw my neighbor masturbating. She was totally doing the toggle toggle whop whop WHOP!
