A lie or lying. Used as both a noun or verb. Derived from Alexander Boris De Pfeffel Johnson (at time of writing Prime Minister of the UK) who on record in the House of Commons seemingly can't stop himself lying.
Ah look, there is that Johnson Borising in the House of Commons again.

Yeah, he said he hasn't taken any Russian money which is a complete Boris. I mean he tells so many Borises a day he can't even keep them straight.

Used interchangeably with the majority of negative and derogatory words. Particularly synonymous with failure, ineptitude, general uselessness and being shit.
"You've managed to completely Boris that up."
"What an absolute pile of Boris."

A kickass metal band from Japan alternating between drone, sludge, stoner rock, groove metal, and sometimes hardcore. They have a shitload of albums, splits, eps, and collaborations with other bands. Not a pussy band like popular j-rock.

Awesome Japanese experimental metal band that also cross over into stoner rock, psychedelia, sludge metal, groove metal, noise rock, and drone metal. They're a three-piece band but are able to create some pretty sick sounds and also enthrall the listener with an atmosphere of ambient, transcendental noise.

Oh! And they're named after The Melvins song Boris.
My friend saw Boris in concert last night, and came back with his mind blown by how amazing they were.

Often confused with a fat old balding russian man, but is actually the coolest and most dashing (; armenian guy ever! He's jams out on his guitar for hours and leaves the girls swooning. He'll never give up on his friends and stays up 'til the crack of dawn talking to them. Everyone wants a best friend  like Boris!    
Mom: who you texting? 
Me: Boris
Mom: oh...say hi for me! 
Me: *texting* my mom says hi 
Boris' reply: :O haha...tell her I say hi back! (-:
The End
