Little Fatty is a Web 1.0 meme developed at least 100 years ago by people who nobody cares about. Basically, it involves an azn boy from China, who is kinda overweight, who had his face shooped onto tons of stuff. He was actually 19 at the time of the picture and was employed as a petrol station attendant.
Although he suffered butthurt over the picture and the meme at first, he has now embraced it with open arms, and became an Internet celebrity in China, but still, nobody gives a fuck. He has the following to say for himself:
What Little Fatty will look like in middle age, if he doesn't look like this already given the age of the meme.
Little Fatty is related to a series on AZNS.
