Tux

Tux can be used as a short form of Tucker, but you're likely more familiar with it as a name for black and white cats. As a pet name, Tux comes from tuxedo — black and white men's formal evening wear. The tuxedo was named after Tuxedo Park, a development for the New York elite and the site of the country club where the tuxedo was first worn.

Tuxedo Park, in turn, is speculated to be named after an Indigenous term. In Algonquian, p'tuck-sepo means "crooked river".

Pronounced TUKS.
