Fatman in the Bathtub with the Blues
In Southern States a euphemism for clitoris is "the man in the boat" referring to the lone passenger in the dory shaped vulva. Many newly weds are determined to sink him. " Fatman in the Bathtub with the Blues" is a reference to an engorged clitoris in need of attention.
I met a woman in a bar Friday night who told me she had a Fatman in the Bathtub with the Blues at home. She wanted to know if I was interested in cheering him up.
