Etymology Origin:
Originally, slicker referred to a waterproof coat (mid-19th century), named for its smooth, glossy surface. The informal sense of a "smooth-talking person" emerged later, playing on the dual meaning of slick—both physical smoothness and social shrewdness. The word’s evolution mirrors how material traits metaphorically describe human behavior.

Beware of slickers offering too-good-to-be-true deals.
