Place this clip at the very end of a self-hype montage as the closing beat, after a rizz sound for the setup and before goofy ahh sounds if you want the edit to collapse into pure parody.
このサウンドについて
This clip is a spoken male voice delivering the line 'I feel so sigma' with an extra drawn-out 'awwn' flourish, stretched over about eleven seconds in a theatrical, self-serious delivery. It feels funny and cringey rather than cool, landing as ironic self-hype. It comes from the early 2020s sigma meme trend that spread through short-form video edits.
