Stolkien

Stolkien is the slash ship between Stan Marsh and Tolkien 'Token' Black from the South Park fandom.

Canon
Tolkien began going out with Stan's ex-girlfriend, Wendy Testaburger, which caused Stan to become jealous and hang out with the goth kids to sulk. At the end of the episode, Stan flips both of them off. Nothing has came of this interaction since it happened.

In the first episode of Season 11, 'With Apologies to Jesse Jackson', Tolkien is mad at Stan because Randy said the 'N' word on live television. Stan tries to claim that he understands how African Americans feel when that word is said, but this just upsets Tolkien more. At the end of the episode, Stan realizes that he will never understand how African Americans feel when the word is said by a white person and Tolkien is satisfied.

In recent Season 25 episode, 'The Big Fix', Randy is inclined to start more diversity in the weed business, so he tells his son, Stan, to hang out with the only male black kid in his school, Token. Stan feels guilty after this and invites Tolkien and his family to dinner. While chatting about different things, Token's name is brought up. Steve Black tells the others that he named his son after the author J.R.R. Tolkien. Stan then realizes that Tolkien's name is 'Tolkien'. In the entirety of the series, Tolkien went by 'Token'. As it turns out, his name has always been Tolkien and Stan is the only one who's been mispronouncing it. He becomes embarrassed over this and begins to obsess over J.R.R. Tolkien's 'Lord of the Rings' and 'The Hobbit' so he could seem like he always knew. Tolkien isn't flattered by this outcome and instead explains that he hates J.R.R. Tolkien's books and doesn't care for them. This leaves Stan even more humiliated than he started. Later that day, Tolkien stops by Stan's room to ask if he was okay. Stan confesses that he thought Tolkien's name was 'Token' and says he understands if Tolkien doesn't want to hang around with him anymore. Tolkien claims that he has not choice but to hang out with Stan because his family was moving into the farm in front of Tegridy. Randy finds out about this and kicks Tolkien out of his house due to his worries that Tolkien is a 'spy'.

As of the opening of Credigree Weed, Randy forbids Stan to interact with any of the Blacks, including Tolkien due to the families rivalry over their marijuana businesses. Instead of listening to his father, Stan rebels and begins to build a friendship with Tolkien and the two become very close.

Fanon
Stolkien did not gain much traction until after the events of 'The Big Fix', which caused a boom of popularity among the fans. While it is nowhere near ships like Style or Stendy in fanart, many fans found themselves dedicated to their relationship. It is often compared to the 'Forbidden Lovers' trope since Randy doesn't want Stan seeing Tolkien, platonically or not.
