A term used to say, "I'm glad that makes you happy,
even though I don't get it myself."
Comes from the term "man in the
boat" referring to the
clitoris and the female genitalia. So, if your boat is floating, you are quite happy.
1: I love eating pigs feet, they sure are tasty.
2: That sounds
nasty, but hey, whatever floats your
boat.
