One screams "O'Douls!" when family members or relatives say sexually inappropiate comments to each other. This stems from the
joke, "Going down on your cousin is like drinking O'Douls. It tastes the same but you know
something ain't right."
When a
male cousin says to his attractive female cousin, "Oh, I'll give you a
pearl necklace."
One's response should be "O'Douls!!!"
