At 1.25 seconds, this clip is already tight enough for reactions and rarely needs trimming. Download the MP3 to keep it available offline, then assign the file as a ringtone or notification tone through your device settings. Its sharp, raspy voice can cut through quiet dialogue, so lower it slightly when layering it over speech. For a two-part reaction, place a shocked sound before the laugh. Check the final mix on phone speakers, since excessive volume can make the brief chuckle sound harsh.
