Uncle Fucka

Background
Uncle Fucka is a song written by Matt Stone and Trey Parker for their movie South Park: Bigger, Longer, & Uncut. The song is sung by characters Terrance and Phillip, where they continiously insult eachother by calling the other names such as a boner-biting bastard, a pig fucker, and, of course, an uncle fucker.

The user DevilsApple, also known as "Th0r", has used this song to spam people who are deemed "shit people" until they are blocked as a punishment for their actions. People who he claims qualify for "uncle fucka-ing" are bigots, factkinners, people who defend factkinners, anti-xenogenders, those who make fun of trauma, etc. Th0r will call those he attempts to make "uncle fucka" others the "uncle fucka army", and will usually summon said army once he is blocked by the person he is spamming.

Use of "Uncle Fucka"
Uncle Fucka has various ways of being spammed, such as: DMing the person the link to uncle fucka repeatedly, tagging them in posts that have uncle fucka lyrics one word at a time (which has caused him to lose followers in the past), and spamming their comments with the link. There are other ways people go about the uncle fucka spam, but these are the main three Th0r encourages uncle fucka spam to be done.

The activity spam is not very common, and has only been done once, to the user ILoveRickAndMorty. A few people got angry at Th0r for this, and a few of his friends claimed his uncle fucka-ing would get him cancelled, but he then jokingly claimed he would "uncle fuck them too".

Origin
The spamming of Uncle Fucka began with the user @ILoveRickAndMorty, however, the Uncle Fucka "meme" had began before that with a user known as @virginbrat, or "Parker". Th0r had tagged them in a now-deleted post asking them their opinion of the song in a mocking manner, which allegedly brought them to deactivation after being made fun of by the friend group for calling minors sluts and using the n-word.
