v. intr. (creatively offensive) defecate, esp. into a toilet. The epithet elicits an image of a puffy, floating, brown log, and further revolts by identifying feces with food. In the latter respect, it resembles the expression, "pinch a loaf."
My girlfriend came out of the bathroom, and I said, "what did you do, float cake?" She laughed automatically, but then after a moment's reflection, looked at me with disgust and said, "ugh, float cake!"
