The 'Sean Murphy's Butt' meme refers to the viral fascination with the physique of MLB catcher Sean Murphy. While playing for the Oakland Athletics and later the Atlanta Braves, broadcast footage and high-definition photography captured Murphy’s prominent glutes in his tight-fitting baseball uniform, instantly turning him into an internet sensation. Social media users, particularly on Twitter and Reddit, began using these images as 'thirst traps' or to jokingly claim they watch baseball purely for the 'plot.' The meme represents a specific subset of sports humor where a player's physical attributes overshadow their on-field performance, becoming a staple in both baseball fandom and general pop culture discussions about athletic builds.
