The Schneid… Is there anything worse than being on the Schneid?
“Schneid” is actually short for “schneider,” a term originally used in the card game of gin, meaning to prevent an opponent from scoring any points. “Schneider” entered the vocabulary of gin from German (probably via Yiddish), where it means “tailor.”
The original sense was that if you were “schneidered” in gin you were “cut” (as if by a tailor) from contention in the game. “Schneider” first appeared in the literature of card-playing about 1886, but the shortened form “schneid” used in other sports is probably of fairly recent vintage.
