The original poster posts a gif, and then creates a looooong comments section all on his own, complete with original stories, reaction gifs, memes, meta comments, movie references, etc. He posts hundreds of comments, acting like every comment is from a different poster. It’s like if TNT woke up and decided to take over CB for a day by typing as fast as he can for six hours straight. (TNT, I mean this comparison in a good way - this Reddit guy is brilliant)

Warning: Typical reddit swears throughout the comments.
