The word gan is a common Mandarin and Taiwanese slang exclamation, roughly equivalent to damn or a stronger swear, and short clips of it being shouted have circulated widely in meme edits and soundboards. Because this version is only a fraction of a second long, it works like punctuation rather than dialogue, marking a moment of shock or annoyance without needing context. Its popularity comes from that versatility, letting creators reuse the same blunt reaction across gaming clips, chat audios and short form videos in many different situations.
