Spengbab is an intentionally poorly drawn, MS Paint version of the beloved cartoon character SpongeBob SquarePants. Characterized by his cross-eyed gaze, jagged lines, and overall distorted appearance, Spengbab first gained notoriety on 4chan and various art forums in the late 2000s as part of the 'shitty fanart' subgenre. Unlike the high-quality animation of the show, Spengbab represents the 'derp' aesthetic, often paired with intentionally misspelled captions or nonsensical sentences to convey a sense of confusion, irony, or surrealism. It remains a cornerstone of early internet weirdness, frequently used to mock low-quality efforts or to express chaotic energy in online discussions.
