Since so many people confuse shitposting with uploading low effort garbage I decided to do some reasearch and to my amazement there is no accurate definition of the term, which may explaining why people don't understand it properly. For me at least it has nothing to do with spamming or being annoying, on the contrary it's the art of creating something that looks shitty but has a lot of meaning and comedic value behind the crappy facade. Even the intentional bad spelling has it's contribution towards extracting a few lols because some words are hard to spell badly and people to still recognize them.
But the best way to get a point across is with an example and the channel High Boi on youtube exemplifies the best of what I call quality shitposting. You can tell a lot of time and creativity went into his movies review even though that's hidden behind an appearance of low quality. If you enjoy having a few lols I highly encourage you to check him out. And as a last confirmation that people really enjoy intelligent shitposting, he's channel blew up from 1000 to almost 1 million subs in a matter of weeks. Some food for thought for all those looking for "quality" to upvote :P.
