Place it right after the entrance shot, then follow it with the classic bruh for a double reaction that keeps the focus on the person walking in. For a bigger group response, add Oh My God Bro Oh Hell Nah next to turn one call-out into a shared reaction.
About this sound
This short voice clip repeats a flat, drawn-out bruh around the phrase look at this dude, delivered like a deadpan call-out to someone showing off. It lasts just under four seconds and lands as amused disbelief, the kind of dry reaction that makes a confident entrance feel suddenly awkward and funny without raising its voice.
