1. any of a world-wide group of agile, flesh-eating mammals of the genus Mustela, related to the stoats and martens, with a long, slender body, short legs, and a long, bushy tail: they feed on rats, mice, birds, eggs, etc.
2. a person likened to this animal, as in a cunning or slyness.
No weasels, ladies!
