Woman who, on account of a case of severe lethargic nymphomania, seldom leaves the confines of her bed. The legs of such a woman, it is conjectured, would slowly begin to fuse into one were her lady tunnel not constantly inundated by wave after wave of avid lovers. This is all very well, you might think, but the nearest shower is in the other room and so she smells of rotten fish.
Larry: "Aah...Suze is such a wonderful woman"
Barry: "Get lost, mate, she's a fricking mermaid, for goodness sake!"
Garry: "Have you both lost your minds? She's made out of latex"
