Bowuigi refers to the fan-created romantic pairing of Bowser and Luigi from the Super Mario universe. While the 'ship' has existed in niche corners of the internet for years, it reached mainstream viral status following the release of The Super Mario Bros. Movie in 2023. Fans noticed a comedic and strangely compelling dynamic between Bowser’s intense villainy and Luigi’s timid nature. The meme typically involves fan art, edited clips, or captions that portray the two characters in a romantic or domestic light, often subverting their traditional roles as enemies. It has become a staple of 'shipping' culture, representing the internet’s love for unexpected and wholesome character dynamics.
