“Baller” gained a new usage on its definition in the year 2022, thanks to Merriam-Webster. As an informal slang term, “baller” describes something “excellent, exciting, or extraordinary,” especially relating to a lavish lifestyle, as in, “It was clear from his frequent trips on his private jet that the actor lived a baller lifestyle.” This usage of “baller” traces back to 2003, but its oldest usage, which denotes an athlete who plays a sport involving a ball, has been around since 1586.
