Shroomjak, also known as the Mushroom Wojak, is a surreal variation of the classic Wojak character depicting a humanoid mushroom with a wide, eerie grin. First appearing on 4chan's /v/ board in early 2021, the character quickly transcended its origins to become a symbol of post-ironic humor and weirdcore aesthetics. Unlike traditional Wojaks that represent specific social archetypes, Shroomjak is often associated with the 'Shrigma Male' parody—a fictional hierarchy superior to the Sigma male that prioritizes fungi and nature. The meme is typically used to convey nonsensical, psychedelic, or unsettling vibes, often accompanied by the phrase 'A m-m-m-mushroom?' to mock feigned surprise or represent existential dread in a digital age.
