Place this clip at the very end of a reaction sequence as the final judgment. Build up with an Oh My God Meme Sound for the initial shock, then add the Bruh Sound Effect, and let this line close the edit without anything after it.
About this sound
A flat male voice says idk man, seems kinda geh to me across about six seconds in a completely unimpressed, shrugging delivery with no music behind it. It feels funny and dismissive, like a casual verdict that something is not convincing or worth taking seriously. The clip comes from Filthy Frank, the Pink Guy era character created by George Miller.
