Conor Mcgregor and Nate Diaz are set to square off at UFC 196 tomorrow night. In order to maximize your viewing experience, I’ve put together the Unofficial UFC Nate Diaz 209 Drinking Game. Play at your own risk.

Here are the rules:

#1: Drink every time Diaz taunts McGregor.

When Nate Diaz rings your bell, he’s going to tell you (and the world) about it. A master of mental warfare, Nate is always looking to chip away at his opponent’s confidence and composure in any way that he can. These antics are usually met with roars of approval from the crowd.

Nate likes to work the body, the head, and the mind. While McGregor has thus far shown great mental fortitude, that could all change if Nate can land some clean shots and frustrate the Irishman from the outside. But his success in doing so may depend on his ability to take McGregor out of the first round and into deeper waters.

#2: Drink every time Diaz celebrates early.

The Diaz mental warfare doesn’t stop at his opponent — he also looks to win over the crowd as the fight progresses. Another unconventional weapon in his arsenal is the act of raising his arms at the end of every round (and sometimes during). As his opponent begins to diminish in confidence, Nate incites chants of “DIAZ!” from the crowd.

Conor McGregor has always had the crowd on his side in every bout he’s fought. But that could all change when Nate Diaz steps into the octagon. And if Nate is able to get to the end of Round 1 and walk back to his corner with his hands raised to the crowd, it’s very possible that chants of “DIAZ!” could begin to fill the arena — and the confidence of McGregor could diminish (but lucky for him, he’ll still have the fighting Irish on his side).

#3: Do a SHOT every time Diaz flips the bird.

A classic weapon in the Diaz arsenal is the middle finger — and in case you’re unclear as to what he means, it’s usually followed up by a “F*ck you!” for good measure. This technique can be used both defensively and offensively, and is usually intended to encourage rage in his opponent (which can occasionally backfire).

Nate has already thrown a dozen of these at McGregor in the short build-up to UFC 196. McGregor himself is no stranger to flipping the bird at his opponents, so it’s likely we’ll see both men simultaneously flipping the bird at some point in the octagon.

If you’re feeling extra bold, do a DOUBLE SHOT if the two fighters flip each other off at the same time. And if they each throw the technique with both hands, make it FOUR SHOTS.

#4: Especially, a SHOT for the Stockton Slap.

If the middle finger can be seen as the Diaz jab, then the Stockton Slap should be seen as the Diaz straight left. Although not as refined a practitioner as his older brother Nick (who famously slapped Robbie Lawler just before KO’ing him back in 2004), Nate has still been known to throw a disdainful slap at his opponents in the middle of his combinations.

McGregor has never faced a weapon like the Stockton Slap, and it may even prove to be the perfect counter to McGregor’s Flim Flam and Celtic Cross.

If Diaz can chip away at McGregor’s confidence, rally the crowd to his cause, and connect with a Stockton Slap the likes of which the world has never seen, then UFC 196 may end up being a very long night for Conor McGregor — and a drunken haze for everyone who decided to play the Unofficial UFC Nate Diaz 209 Drinking Game.

Expect to finish a pint each round, and most likely down a few shots before the bout even starts. If you can black out before either McGregor’s or Diaz’ head bounces off of the canvas, you win!
