Place this clip at the reveal in your edit, just after the photo or brag appears on screen, then follow it with a bruh reaction to sell the disbelief, and finish with an emotional damage sting if the target looks properly embarrassed on camera.
About this sound
This is a short three-second voice clip of someone loudly shouting the cheeky demand 'Show me your willy!' in an exaggerated, playful tone. It feels rude, silly and instantly embarrassing in a funny way, making listeners cringe and laugh at the boldness of a line nobody would expect to hear out loud in a normal conversation.
