Place this clip at the very start of a standoff edit to set the dare, then cut to the first movement and follow it immediately with the bruh sound effect or the game show buzzer sound effect to mark the loser.
About this sound
This is an 18-second voice clip built around the single taunting line 'whoever moves first is gay' spoken as a dare. It creates instant awkward tension, because everyone freezes and waits for someone else to flinch, speak or shift first, turning the smallest movement into the payoff.
