YouTube Comments 

Such a cesspool of illiteracy, misogyny, racism, idiocy, hatred, violence, barbarism, intolerance and general lack of humanity has not been seen since the middle ages.

Youtube comments, approach with caution lest you wish to be stripped of all that makes you human. The unreputable proof that there has been no evolution, god made us retarded.

YouTube Lightsaber

The red and green bar under a YouTube video that shows the number of likes (green) and dislikes (red) which closely resembles a Lightsaber from the Star Wars films. More green than red makes it resemble a Jedi Lightsaber and more red than green makes it resemble a Sith Lightsaber.

So many people dislike this video that the red YouTube Lightsaber looks like Darth Vader's Lightsaber.

When watching a videos on Youtube and clicking from related video to related video until you have no idea what you originally searched.

Guy 2: "Hey, what did you do last night?"
Guy 1: "Well, I was watching drag racing videos and eventually got Youtube lost, and ended up watching a video about how to properly breast feed..."
Guy 2: "Wow..."

YouTube Rewind 2018 

The most shittiest and worse YouTube video ever. Having more cringe then even Justin Bieber and Fortnite combined, this video can give you any kind of disease if you watch it. This video has almost more dislikes then what Baby from Justin Bieber has, meaning that it's very shitty. Don't watch the video unless you want to die from cringe, and make sure to dislike it.

YouTube Rewind 2018 has the most cringe in a video then I've ever seen before!

YouTube Hipster 

A person who will boast or brag about seeing a video on YouTube before it became popular and got a lot of views.

Regular person: "Dude, I saw that Evolution of Dance video on YouTube last night; that video has almost 170 million views! That guy is pretty good!"

YouTube Hipster: "Yeah, I remember watching that video before anyone was talking about it. It only had, like, 5 thousand views at time..."

Regular person: "I hate you."

Youtube Session

When a group of friends sit around a computer and share youtube videos that they have found in the recent weeks, and take turns sharing said videos.

In a Youtube Session, there is an unspoken rule about taking turns, usually in a round robin style, but is often broken when someone exclaims that everyone "has to see" the video they have in mind.

An abbreviation of "Youtube Session" would be "Youtube Sess", with "Sess" pronounced as "Sesh".

"Charlie, great Youtube Session the other night. I didn't know about Wombo Combo until Heather showed me."

"Oh, my, god. You NEED TO SEE THIS VIDEO, TIME FOR A YOUTUBE SESSION"
