The 'Dude Weed LMAO' meme is a catchphrase and reaction image used primarily to mock stereotypical stoner culture and individuals who make marijuana their entire personality. Often associated with a distorted or laughing image of actor Seth Rogen, the phrase gained traction on imageboards like 4chan and Reddit as a way to satirize low-effort humor surrounding cannabis use. It is typically deployed ironically to highlight the absurdity or repetitive nature of 'stoner' jokes, though it has occasionally been adopted by the community it originally parodied. Today, it remains a staple of internet irony, frequently used whenever someone tries too hard to seem edgy or 'chill' regarding substance use.
