One of the more disturbing videos goes like this: A naked man is in his kitchen with a glass jar on the floor. He squats over it so the jar goes up his ass. When it finally disappears, it shatters inside his ass. He then calmly proceeds to pick the broken shards of glass out of his profusely bleeding ass instead of calling 911. He does this without making a sound the whole time until he gets up and walks away and probably realizes he will die of internal anal bleeding and screams.

While it should be named 1 guy 1 jar, most people refer to it by the cup referencing
Person 1 "Hey friend, let me show you this video called 1 guy 1 cup"

Person 2 "This better not involve eating shit"

Person 1 "No worries dog, lets watch it"

1:30 later

Person 2 "Ur fucked up dude"

Person 1 "lol"

The story of a true Russian hero.

1 guy 1 cup is a video of one Alexey Tatarov, who squats over a glass jar, sliding it up his asshole. The jar shatters inside his ass, and then for the rest of the video, he is shown pulling the glass shards out as it bleeds profusely. One of the most disturbing aspects is the fact that he doesn't even scream, or make a sound. All you can hear is the glass shards crunching in his insides.

And for those who think he died from it, no he didn't. The dude fixed himself up after recording and went to work an hour later, like a true Russian.
Guy 1: Just watched 1 guy 1 cup, I think I'm gonna gouge out my eyes.

Guy 2: Ugh. Same bro.

When you gaze for long into an abyss, the abyss also gazes into you.
"I heard Tommy burned his eyes out with a lit cigarette after watching 1 guy 1 cup. The doctors at the clinic said that he still hasn't stopped screaming."
