The sound comes from the seagull gag in Finding Nemo, released in 2003. In the German dub of the film, the birds repeatedly yell "Meins," making the moment especially recognizable to German-speaking audiences. That short quote spread online because it is easy to loop and instantly communicates greedy group behavior. It still appears in meme edits, reaction videos and chat jokes whenever many people fixate on one thing at the same time.
About this sound
The German seagulls' "Meins" cry from Finding Nemo, used in memes, reaction edits and chaotic clips whenever everyone wants the same thing.
This clip is the sharp, repetitive "Meins" shout from the seagulls in Finding Nemo, taken from the German version where they cry "Meins" instead of "Mine." It sounds fast, greedy and slightly ridiculous, which is exactly why it lands so well in edits. The moment instantly gives a scene a swarm-like, competitive energy, as if a crowd has locked onto one target at once. Viewers usually read it as playful chaos, obsession or a joke about people fighting over food, money, attention or any obviously desirable item.
