Place it right after the on-screen claim that you belong to the group, so the cut lands as the answer. Follow it with sad violin for the friend left behind, or with Nelson Ha Ha when the edit is mocking the claim instead of mourning it.
About this sound
This 14-second Malay voice clip delivers the line jangan anggap aku member korang, meaning do not treat me as one of your friends, in a blunt, slightly annoyed tone. It feels like a dramatic overreaction to a social slight, serious on the surface and funny because of the distancing. The phrase comes from informal Malay, where member means a close friend and korang means all of you.
