Arthur Morgan is the protagonist of Red Dead Redemption 2, Rockstar Games' 2018 western epic, performed by Roger Clark. His laugh comes from the game's quieter camp scenes, where the hardened outlaw lets his guard down around the Van der Linde gang. Fans clipped these moments and the chuckle spread across TikTok, YouTube shorts and gaming memes as a shorthand for rough, genuine amusement. It endures because it carries Arthur's whole character in three seconds: gruff on the surface, unexpectedly warm underneath.
