desperado

A bold outlaw, especially one from southern portions of the Wild West.

The kind of persons who excite or give signal to such revolutions — students, young men of letters […], or fierce and justly bankrupt desperadoes, acting everywhere on the discontent of the millions and blowing it into flame, — might give rise to reflections as to the character of our epoch.

Surely this was the face of a desperado.

A person in desperate circumstances or who is at the point of desperation, such as a down-and-outer, an addict, etc.

The shortstops and desperados were not permitted to play in this marker crap game.

A person who is desperately in love or is desperate for a romantic or sexual relationship.

A piece that seems determined to give itself up, typically to bring about stalemate or perpetual check.
