The feud started with slow-play and it reached its height with an eye-roll.
Now high-rollers Brooks Koepka and Bryson DeChambeau will settle it at The Match over 12 holes in Las Vegas.
They are playing at the Wynn Golf Club on the Las Vegas strip not far from the blackjack, roulette and poker tables.
Koepka and DeChambeau will peg it up at 4pm ET on 26 November.
The chips will be wagered and both will be going all-in.

What is there to know about the Wynn Golf Club?
It has an interesting history.
Tiger Woods and Jack Nicklaus are just two big names who have won here before.
That victory came after Woods announced: "Well I guess hello, world". He never looked back.
Yet back then - in 1996 - it was called the Desert Inn Golf Course.
Since then, it was purchased by Steve Wynn and redesigned by Tom Fazio.
What else? Water comes into play. A lot. In fact, the wet stuff is in play over 12 holes. There are also reportedly more than 8,000 trees on the landscape.
The 18th also offers up a thrilling finale. It's a par-3. And from the tips it can be played from 249-yards. This is to a green which boasts a 35-foot waterfall behind it.
Sadly, we might not get to see this in The Match as it's only over 12 holes. But possibly it could feature in a playoff? Who knows.
The Wynn is a par-70 layout. There are six par-3s and four par-5s. If you're playing from the tips it can measure at 6,722 yards but can play as short as 4,810.
Although Las Vegas is clearly tailored for the high rollers and this looks like an exclusive property, it's also open to the public.
But it comes at a price.
It will cost you $550 for a green fee in-season.
You also might be thinking, why is this only 12 holes? It's reportedly to do with which holes will look best on camera.
