Place it at the end of a reveal, right where the name is spoken, then follow it with Bruh for the reaction. For a bigger fallout, put Emotional Damage after the name instead, letting the call-out set up the over-the-top response that follows.
About this sound
This is a sub-second spoken name, just the two clipped syllables of Shibu in one brief burst. It lands as a dry, unexpected interruption, funny because it arrives with no warning and leaves nothing to explain. The abruptness makes it feel like a pointed call-out, a small jolt that cuts through a quiet moment and keeps the focus on whoever has just been named.
