Place this clip as the closing beat after the mistake itself, not under dialogue. For a longer fail sequence, lead in with the enemy spotted sound to set up the threat, then finish here, or follow it with the nope sound for a flat rejection.

This is a short 2.6-second clip of GLaDOS delivering a slow, deliberate clap, her flat robotic applause dragging out each hit. It feels dryly mocking and unimpressed, like praise offered only because a terrible effort demands a response. The moment comes from Portal, where the AI overseer uses it to belittle the player.
