Place it as the reply beat after a setup line, not as the opener. Follow it with a bruh sound for a second reaction, or lead into it after an emotional damage sound when a bad take needs a short answer before the next cut.
このサウンドについて
This clip is a short male voice line saying yeah man in a relaxed, drawn-out way, tagged here as Theago. It lands as easygoing and amused rather than excited, like a casual yes that also pokes fun at how obvious the agreement is, which makes the delivery feel laid-back, confident and a little cheeky in conversation.
