Full Boat — a slang term for a Full House, a poker hand consisting of three cards of one rank and two cards of another.
Explanation. In poker, a Full Boat (also simply called a “Boat”) refers to a Full House—a five‑card combination made up of three of a kind plus a pair. For example, holding 7‑7‑7 and J‑J gives “Sevens full of Jacks.” It ranks just below Four of a Kind and above a Flush in standard poker hand hierarchies. The term “Boat” likely originates from riverboat gambling in 19th-century Mississippi, later becoming popular as casual slang for a Full House.
