At 1.25 seconds, the file is already compact enough for rapid reactions and usually needs no trimming. Download the MP3 to keep it available offline, then assign it through your phone’s ringtone or notification settings if that format is supported. The spoken line cuts through most quiet footage, but lower it beneath close-miked dialogue to avoid masking words. For a two-beat reaction, place a Bruh sound effect or game show buzzer after it, leaving a small pause so each hit remains clear.
