The exact origin of NBA Tanto is unclear from the available metadata, and it does not have a widely documented source credit attached to the name alone. Online, it appears mainly as a short basketball-themed reaction sound passed around on soundboards, repost pages and meme edits. Its staying power comes from how easily it fits sports content: a quick audio cue can make a simple crossover, block or staredown feel bigger, funnier or more intense without needing a long setup.
