The 'Doobie Ralsei' meme features the character Ralsei from Toby Fox’s game Deltarune smoking a large joint (or doobie). The image first gained traction in late 2021 as a subversion of Ralsei's established persona as a kind-hearted, innocent prince. The visual of a wholesome character engaging in drug culture became an instant hit on platforms like Twitter and Reddit, often paired with ironic captions like 'This goes hard' or 'Feel free to screenshot.' It serves as a quintessential example of internet contrast-based humor, remaining a staple in the gaming community for reaction posts and shitposting.
