A person that makes shit happen. Without additional context, "baller" typically is assumed to imply demonstrated ability in generating prodigious amounts of cash money, and/or a proficiency with creating frequent and mind-blowing sexual opportunities (note the non-gender specific reference, implying that ballers can be men or women, gay or straight -- it is a matter of perspective).

In modern usage, baller does not refer to sports ability -- although the term is likely to have originated with basketball. Still, the reference to "game" is important to the definition of a baller. A baller must have game. A mad baller must have mad game. (Here, game is referenced according to the current definition (which pretty can mean pretty much anything, but generally refers to business, social relationships, or desired activities in general).

See also: Mad Baller; Game; Pimp; Rock Star
usage:

Cat 1: "That cat is a baller. He just (sold $1m of stock | bought a Ferrari | scored backstage access | flew first class | got on a bus full of supermodels | etc.)

Cat 2: "Yeah -- he's got game. Mad game."

Cat 1: "Agreed. He is a mad baller"

Cat 2: "Word."

this is old 70 s and early 80 s slang for dealers who sold eight balls of cocaine.. it went on in the late eighties to mean anybody who is rolling in money and dealing in drugs... in the early 90s it was attributed to rap stars and anybody who was just rolling in the dough... It is currently (after late 90s) attributed to ball players rolling in the dough.

Baller is a meme showing an image of a Roblox character holding a ball in a position that is aiming toward you, about to throw the ball. The character's design is that he wears a red shirt and black pants. His skin is yellow, similar to that of the Roblox noob's skin color, only just a bit brighter. The face he uses on the head is called "Fearless", and he holds a red ball in his right hand.

Yes, this meme is incredibly unfunny as hell. I don't get why people think that it's the funniest shit ever.
Guy 1: Baller.
Guy 2: STOP POSTING ABOUT BALLER! *VineBoom sfx plays*

One of the 4 warriors in Boss Fighting Stages on roblox, who would be later turned into a meme via “stop posting about baller”. Baller’s dynamic weapon is the dodgeball. For his level 25 attack, he throws 3 balls at once. For his level 50 attack, he throws a giant super ball. Judging by the dialogue, Baller seems like a chill and confident person in battle. He also has the ice spirit (Dezadon) as his sparring partner.
Hey, have you played BFS? I usually play as Baller.

Used to describe someone who's got a bit of cash, got the girls and has ascended. Mostly used as a joke. Also counts on roblox. When you reach baller level 69 you know you've got all the clout and the girls.
Dave: I've ascended, I have a girl and some cash, I'm a baller now mate.
Dean: What's your baller level on Roblox Dave?
Dave: 69 mate.

Dean: It's true, you really are a baller.
