Brooklyn T. Guy is a recurring character in SuperMarioLogan, a puppet comedy series on YouTube where he plays many different jobs, from police officer to doctor, and often ends up dealing with the main characters' chaos. His weary uh oh became a handy shorthand online, shared as a short clip and soundboard button for moments of dawning trouble. Like a shocked sound, it works without context because the tone alone signals that something has gone wrong, which is why editors keep returning to it for reaction videos, memes and short-form clips.
