Celtics game
Definition
A basketball match or competition involving the Boston Celtics, a storied NBA franchise from Boston, Massachusetts, famous for 18 championships, leprechaun mascot, and green-clad fans who treat every possession like a personal vendetta.
Informally, any high-stakes hoops showdown where the Celtics' luck-o'-the-Irish defense either shines or shamrocks the competition.
