Place it right after the reveal that gives the player away, then follow it with French Meme Song to close the sequence, or put Enemy Spotted just before it to set up the catch.

This is a two-second French voice clip saying 'Ho, il m'a eu' in a caught-out, resigned tone, as if the speaker has just been spotted or beaten in a game. It feels playful and self-deprecating, turning a small defeat into a light, knowing laugh rather than frustration, and it works best as a quick reaction to being caught.
