If you say the phrase 'You don't know me but I killed you're brother,' your actually telling that person you kicked their cat and you're very sorry.

A cringey phrase being used by the cretinous Instagram-generation to devalue another person's opinion about football. Regardless of the fact that the validity of that person's opinion usually spot on.

The origin of this phrase is hazy but it came in after those of the age 22 years and under decided to start using unnecessary Americanisms to describe the English game in an effort to sound cool. Thus the term "ball" came in at the expense of the term "football".

See also "baller" e.g "dude that Kevin De Bruyne is a propah ballllller". Just stop thinking you're American you plums!
Nigel "Harry Kane doesn't show up at finals or semi-finals. He's decent but he is nowhere near world class. The statistics back me up on this"

Instagram obsessive clueless oik "you don't know ball fam- he is world class so put sum respeck on da name. I don't care about statistics or facts I just think my opinion is as valid as your facts. Plus I say actually and literally a lot"

A phrase used to let someone know their opinion is garbage.

"You wrote an entire novel about why this phrase is stupid? Wow...you don't know ball.

You don’t know anything about anything, or jack shit. It means you’re so out of the loop, you don’t even know Jill, let alone Jack. Like are they siblings? Dating? What’s the situation? You don’t know. That’s how lost you are.
He was tryna act like he knew what went down last night… boy, you don’t know Jill about Jack.

This is a catch phrase that originated in a TV ad in the late Eighties that featured super athlete extraordinaire Bo Jackson and rock'n'roll pioneer Bo Diddley (he's notorious for his famous box-shaped electric guitar). Basically, the term means that somebody doesn't know doodly squat.
The narrator says:
Bo knows football.
Bo knows baseball.
Bo knows weightlifting.
***********************
In the meantime, Bo Diddley cranks out the notes on his guitar.
Then he says:
Bo, you don't know diddley!
