Definition: a flirtatious woman
Technically, an equivalent male is a “coquet,” but you don’t see that word much.
Perhaps unfortunately, “coquet” is a diminutive form of “cock” in French. One assumes that the usage here is because a rooster “flirts” with a bunch of hens. That would fit a male in this situation, and “coquette” is the feminine form of that.

A book describing a woman in a James Bond movie said she would do something, “in classic coquette style.”
