Jock Stan

Jock Stan is a shorthand for a perceived tendency among fanfic writers to portray Stan Marsh as overly masculine, macho, jockish, or obsessed with sports. It is often used inclusively of any flaws associated with fandom portrayals of Stan, such as portraying him as depressed and suffering from alcoholism. 
It is a common subject of criticism of the South Park fanbase and is widely perceived as ubiquitous of all fanfiction writers. The label carries an inherently negative association and is intended to disparage authors for portraying him as Out of Character.
It has been a claim since the mid-2000s that the vast majority or even all South Park fanworks depict Stan as overly jockish and Kyle as overly nerdy, stereotypes which are mocked on a daily basis, including as a meme, and occasionally subject to thoughtful deconstruction.
It has been used occasionally as a tag on Archive of Our Own
