A person who finaggles; someone who obtains things through cunning schemes, manipulation, or clever deception.
From finagle plus -er (one who does). This term emerged in American English to describe people with a talent for clever manipulation and scheming.
A finagler is basically a clever schemer—the kind of person who can talk their way out of anything, convince their parents they deserve extra allowance, or find loopholes nobody else noticed!
