it is a video, where a naked dude sits on a jar and it just breaks in his ass and it bleeds. its like a weird dildo testing
after seeing 1man1jar i think that a glass jar is not suitable for a dildo

Get the 1man1jar mug.
The most gruesome, unholy terror ever to befoul the Internet, at least until someone comes and inevitably tops it, as it did its predecessor.
I became an atheist the day I saw 1man1jar.

2girls1cup seems like softcore cable porn now that I've seen 1man1jar.

A dumbass who shoves a jar up his ass like a butt plug, his ass bleeds and blood comes out, it's fucking disgusting
Guy 1 (on the internet): Ooo, what's 1man1jar?
Guy 2: NO DON'T WATCH IT, AW MAN C'MON!
