The line comes from Disney's The Lion King from 1994, spoken by the villain Scar as he grows frustrated with the hyenas around him. Long after the film's release, the quote lived on as a reaction sound, shared in memes, short videos, and edits whenever someone wanted to call out foolish behaviour without a long explanation. Its staying power comes from how universal the sentiment is, since almost everyone has felt surrounded by bad decisions at work, at school, or in a game lobby.
