The phrase here we go is a common English expression for starting something, and stretching the final word gives it a louder, more theatrical feel that fits short-form video perfectly. Because it is instantly recognisable even without context, creators have reused it across gaming clips, reaction videos, sports edits and meme compilations as a universal signal that something is about to happen. Its brevity also helps: at under two seconds, it can sit between scenes, over a title card or at the start of a montage without slowing the pace, which keeps it useful long after any trend fades.
