I think the author was right that its 4chan language. I wouldn't say its a product of being on Reddit. Besides /r/the_donald and /r/wallstreetbets/, I've only ever seen that kind of language on 4chan-specific subreddits like /r/greentext and /r/4chan.

Some of the gun subreddits mimic this language as well. Particularly weekendgunnit before they went off platform.
