Place it right after the failed lift, missed shot or bluff that falls apart, then follow it with Emotional Damage to pile on the failure or Bruh when the flop needs a flat reaction first.
About this sound
This is a short spoken taunt in which a voice delivers the line 'I thought you were stronger' with flat, unimpressed disappointment. It feels mocking and dismissive, as if the speaker expected far more and got very little. That flat tone makes the judgement feel final, turning a small stumble into a joke the whole room can laugh at.
