This guy means what he says.
It appears that a Russian man was killed by his friend in a fight over a woman. Nothing special in that, but the way he did it, well you'll have to read and watch.

Russia – Alcohol and jealousy caused a 28-years-old man from Nizhny Novgorod to murder his friend in a very weird manner. He literally shove his foot up his friend's rectum, causing serious injuries and internal bleeding, from which the man died.
Say what you want about this dude but he's not letting anybody call his bluff. He says he's gonna shove his foot up your (butt) then he's gonna shove his foot up your (butt) plain and simple.
This isn't a game. There's no hyperbole or exaggeration here. This is Russia mother(grabber). No smiles. All business.
You mess with Vladimir Krasnov's girlfriend then you better sleep with one eye open. Because you let your guard down and next thing you know you'll have an (butt)hole full of foot and you'll be dead.
And I'm pretty sure that means you lose the argument. Checkmate bro.
PS – The girl looked pretty broken up about the whole thing huh?
