The phrase is closely associated with Mario and is widely recognized from Nintendo games, including the Super Mario 64 era in the mid-1990s. Short clips of Mario's voice became popular in memes, gaming montages and soundboard culture because they are instantly readable even out of context. “Let's-a go” still gets used in edits because it is upbeat, family-friendly and strongly tied to retro gaming nostalgia. It often appears alongside other goofy reaction sounds such as bruh when creators want a quick comedic switch.
