Someone who posts a meaningless video on YouTube.

When you eat dirt for the first time and leave your family to build a shack in the woods

Name given to all the idiotic people who post comments on Youtube.

In the farewell stage of an exchange of greetings and/or pleasantries, a 'you-tard' occurs when one party replies "you too!" when it does not apply.

A person on YouTube who posts idiotic comments, generally they sound like they're insane or suffer from a mental disorder. They don't sound like the average commenters on YouTube and they don't provide helpful comments or start mature discussions. The majority of them are the 12 year olds that have invaded the internet and are generally trolls. Using insults like: gtfo nub, ur a scrub, get rekt m8, or the favorite of them all "ur mom". Replying to questions with "Darude-Sandstorm". These kinds of people generally love the most popular YouTubers and will defend them at all costs.

There's been a great rise of 'YouTards' after 2012.

Similar to a poster of 4chan's /b/ section otherwise known as a /b/tard.

The large number of people that comment on youtube videos who do at least one of the following: troll, lack proper grammar/spelling skills, post ridiculously stupid comments that prove they have a low iq, or ask people to give them a thumbs up...
