Flinstone Vitamin

When you commit fellatio on a female during her period while its marinated by flavored lubricant to offset the mettalic flavor, thus resembling the flavor of a Flinstone Vitamin.

Person 1: "Babe im on my period but can you eat me out?"

Person 2: "Oh hell naw bitch i dont need no Flinstone Vitamin I took a One a Day Mens."
