Lying thug Taylor Martin stabbed a friend with a kitchen knife then dragged him by his hair into the street and left him with part of his stomach hanging out.
The 23-year-old then blamed the vicious attack on two strangers – which resulted in an innocent 14-year-old schoolboy being arrested and questioned.
Martin was caught on police bodycam footage smirking and telling his fictitious account as Tarren Laughton was receiving treatment for his life-threatening injuries.
But a jury at Canterbury Crown Court rejected his defence and ruled that he had been the ruthless knifeman.
Now Martin, of St Francis Close, Whitstable has been given an extended 21 year sentence for the drunken attack.
It means he will have to serve more than 11 years before he can even be considered for parole – but may serve the full 17 year jail term.
He will then be on licence for the remainder of the 21 years.
The jury had heard how the men had been drinking with Martin’s girlfriend but fell out about Mr Laughton buying all the booze.
Martin, who had denied the wounding with intent charge, was then given a 12-inch kitchen knife with a pink handle and thrust it into Mr Laughton’s stomach.
Prosecutor Kieran Brand told how the thug then twisted the blade as part of his victim’s intestines came out.
But despite that, Martin continued punching, kicking, and stamping on his victim before dragging him outside and leaving him in the street.
Judge James O’Mahony told him he had carried out a "bizarre charade" after the stabbing when he was caught on film "smiling and grinning as (you) acted out this false account."
He added: “Your victim, who had been your friend, needed emergency treatment and has been profoundly affected, leaving him fearful of going out.”
The attack happened just weeks after Martin was caught speeding through 30mph streets at 55mph, going through red lights and not stopping at roundabouts, forcing pursuing policed officers "to drive like it was a Formula One" race to keep up.
After crashing into a lamppost he laughed at police officers telling them: “You got me, I was driving” before asking for a cigarette.
