mink

Wise, mischievous, clever and naughty. A 'cheeky' trickster (n.), or (adj.) used to describe something riddled with contradictions, surprises and intrigue. The term has evolved to describe everything from an unclean denizen on the street who may also be an expert secretly in the know, to the opposite of anything related to wealth, excess and exclusivity - often to do with sex.

* Irony: Many usages of mink are usually in direct conflict with an opposite usage or meaning; therein lying the irony. Often the meaning can change depending on the context and tone.

* Origins (many): In British slang, "minky" can be used to describe a woman's desirable sex or her genitalia directly ("mink" or "minky"), and can sometimes also be found used in combination with "cheeky monkey". Also related is "minger" used to describe an undesirable and unseemly woman or her sex directly; a "Minx" is a "pert, flirtatious and impudent young woman". In Native American folklore, the reputation of the actual animal's spirit in is known as a trickster and fire-starter, much like the coyote.
Don't trust that little mink. She knows everything, but won't tell you.
