English word name or nickname"two"
Deuce Origin and Meaning
The name Deuce is a boy's name meaning "two".
Basketball's Jayson Tatum introduced this to the naming lexicon when he used it as a clever nickname for his son, Jayson Christoper Jr. It fits in with nicknames like Trey or Trip for boys who are the third in the family with their name; we've even heard Quatty and Quinto.
