The weird part of Youtube 

The weird part of YouTube is typically an area full of video irrelevant to what you were originally watching. These videos would normally go untouched, but become popular when a significant amount of people follow of a chain of "related videos" into said area of YouTube. These videos usually have misleading titles and thumbnails, or are just plain... weird.

Since most people become confused when they somehow cross into the weird part of YouTube, they share the experience by commenting about it, usually to find that a great many of YouTubers have also reached this conclusion

"I was watching a video about Gary Coleman and 5 'related videos' later I got stuck in the weird part of Youtube."

"Somebody help me! I've been stuck in the weird part of Youtube for 5 days! I'm surrounded by deformed babies and old people!"

"Somehow I stumbled into the weird part of Youtube and I've never wanted to punch something so badly."

Normally reached by endlessly clicking on recommended videos, the Weird Part of YouTube can also be reached in the vice-versa sense, as in once you're there, you can also endlessly click of recommended videos to get out. See paradoxical loop.

After more than three hours of watching recommended videos, Randy Marsh had finally reached his ultimate goal: the Weird Part of YouTube.

Cue the Internet Shortage episode of South Park.

The YouTube jungle. A desolate zone littered with video uploads generally taken down within two weeks due to strange and/or NSFW content. The users have unintelligible names and post videos that make no sense.

When your sleepy and accidentally end up watching a Boku no Pico episode because it was on the Up Next list automatically.

Person 1: So I was watching this cool video, but it ended so I let the Up Next video start ‘cuz I thought it’d be related. But it was a vid filled with gay shat.

Person 2: Oh no... you’ve fallen into the weird part of YouTube...
