Barf Simmons, also spelled Barf Symptons, is a series of Simpsons memes built around a blue, elongated version of Bart Simpson rendered in a creepypasta-flavored horror aesthetic1. The character has bluish skin, a green shirt instead of the usual orange, and a stretched neck, usually shown in grainy low-light footage1.

The format covers still images of the character lurking in alleyways and more elaborate video edits that splice Barf into low-quality clips from other cartoons like Family Guy3. The lo-fi look and off-model design are the whole joke, sitting somewhere between analog horror and a shitpost.

Barf Simmons edits typically drop the blue, long-necked Bart into existing meme footage or Simpsons scenes, often over grainy VHS-style filters and ambient horror sound. Creators commonly recycle recognizable clips (the Robert Loggia bit, Family Guy cutaways) and swap in Barf where a character would normally appear, letting the off-model design carry the unease.
