compost critter
An extremely unattractive woman, the compost critter is a nocturnal creature that creeps through bars looking for her next victim to take home, and rarely takes 'no' for an answer. The compost critter is rotund, with nappy hair and an oily face. Some have described the compost critter as a mix between the mud turtle and the cougar.
I would never hook up with her; she's a compost critter.
