The sound comes from Pixar's Finding Nemo, released in 2003, where a flock of seagulls perched near Sydney Harbour repeatedly shouts mine as they compete for food. The scene became one of the film's most quoted moments and was quickly clipped, remixed, and reused across YouTube, TikTok, and meme edits as shorthand for greed and group chaos. Its simple, instantly recognisable chant works without any context, which is why creators still reach for it two decades later whenever a crowd turns selfish.
