Autism
"Autism" is internet slang used as a broad insult targeting online fandoms and communities whose members are viewed as too obsessive or socially awkward. The usage grew out of imageboard culture in the late 2000s and early 2010s, and reached mainstream visibility in 2012 through celebrity tweets and fandom disputes.
Overview
"Autism" as an internet term refers to the use of the word as a broad insult aimed at online communities, particularly fandoms whose members are viewed as obsessive or socially awkward3. Posters apply it to users who show too much enthusiasm for niche interests, treating that enthusiasm as a symptom of the developmental disorder that shares the name.
The slur sits alongside "cancer" and the "-fag" suffix in a family of catch-all imageboard put-downs used against whole subcultures rather than single people3. Urban Dictionary entries pushed back on the trend, with autistic contributors writing definitions insisting the word "is NOT an insult used to call people idiots"2.

How to Use This Meme
The insult is typically dropped in reply to displays of extreme fandom devotion, obsessive collecting, or long enthusiastic posts about niche subjects. Common variants include "peak autism" or "highest form of autism" attached to particularly over-the-top examples, as in the 2012 brony mural graffiti4.
