who's tried it? what does it taste like?

I'll pass on the Billie Irish.

fart sound

I mean it probably tastes like eating out an unwashed diabetic gamer girl, but I've probably also had worse. I'll give it a shot and report back in a couple of days.

That's a very specific descriptive, tell me more.
- Minge tastes vaguely of copper. Guinness also tastes quite metallic.
  
  Gamers drink a lot of energy drinks
  
  Diabetics secrete sugars in fluids that wouldn't normally contain sugar.
  
  Unwashed because beer is fermented, just like my true loves lady bits.
- Michael Scott No Meme!
- Bro is already triggered.

I consider this to be a hate crime against my people.

I consider this a hate crime no matter the people.
Imagine what the Guinness people are thinking about this...
- I am the Guinness people. ^^
This is definitely a hate crime against gamers.
It's not a hate crime the first time.

This is what Brexit did to Ireland.

Where my hydro homies at in these times of need?

Water for life
- Ukrainian water, da. будмо

Have you ever taken such a big shit that you had to remove your pants and underwear so you could open your legs wide enough to shit it all out faster? I imagine drinking one of these feels something like that.

The Billie Irish

Seriously, make this name a thing if it isn't already

How is monster denser than Guiness...

Guinness isn't that heavy for a stout. Monster will have a ton of sugar as well.
Nitrogen gas
- Pretty sure CO2 is more dense than nitorogen.
  
  Nitrogen also doesn't like to dissolve in water so as to why they add it make no sense to me
  
  Source, I brew beer

It tastes like blood because you're going to get punched in your potty mouth for ordering it.

Liver failure.

Cobra's Venom
- It's cobra's mist you trole twu

Just guessing, but looks like it tastes like GUINESS -> briefly ass -> MONSTER WRECKING MY BUZZ.

this looks fucking radioactive

Heart attack juice

stuff like this is done in Czechia, which is the country with by far the most consumption of beer per capita.

Diesel is Coke and Beer.

then there is Sprite and Beer.

I am pretty sure Fanta and Beer is a thing too.

plus there are various syrups that can be added to beer, Cherry, Strawberry and Elderberry are the most popular of those

Diesel is equal parts cider and beer with a dash of blackcurrant. Turbo diesel also contains a shot of vodka.
- That just sounds like Snakebite and Black, a drink most places in the UK won't serve.
  
  Mostly because cleaning bright purple vomit out of your pub carpet is a fucking nightmare.
Beer and Sprite is called Radler in Germany, meaning cyclist because it's often drunken during weekend cycling tours when you don't want a full beer
- It's beer and lemonade in Italy
- Radler has recently made its way to Korea. I bought some once not knowing what it was. While drinking, I couldn't figure out why I wasn't getting a buzz. I thoroughly checked the can and found out it's got 2-3% alcohol. Needless to say, I haven't bought it since.
7up and beer is a Snowwhite in the Netherlands, but nobody's ordered one since the 80s

What a terrible thing to do to a Guinness

Is Guinness supposed to be good? Or just everyday average you can count on to get a decent buzz on.
- It's known more for being smooth, not really a beer to just get trashed on, but you definitely can.
- I enjoy it. Good texture and slightly above average taste for the price in my opinion.

Tastes buds: Hell YEAH!!!

Heart: Da fuq!?!?! ..----.....-----...-.... X_x

Ever tried shandy? It's basically that, but Guinness.

The sweetness of the Monster is countered by the stoutness of...the stout, basically making a shandy.

Wash your mouth out with radioactive waste you dirty Philistine.

Shandy is fine on a hot summer day if you have to drive. Pleasant, even.

That drink is the greatest assault on the Irish nation since bloody Sunday.

It must taste like sadness

Irish gut bomb.

Okay That's seriously looks like a radioactive diarrhea.

I didn't try it, but I can confidently answer your question anyway:

Ass.

Is this legal?

IFF (if and only if) I were drunk enough already, only had Guinness in the fridge (don't like the stuff anyways), and also had monster on hand (yeah I drink it instead of burnt bean juice), I would try this.

If it ever happens I'll try and remember to post my thoughts.

If your bean juice is burnt, you made it wrong. Turn off the hot plate as soon as it's done brewing in traditional drip style. Primary cause of burnt coffee.
- That's a good tip, but I assume he meant he drinks juice of burned beans, rather than burned juice of beans. After all, coffee beans do need to be roasted (burned) before you use them!
- I've tried many different kinds of coffee that people have sworn by.
  
  If they weren't 90% sugar, the burnt taste/smell overpowered everything else.

Not exactly the same but on New Year's I created this monstrosity. Green food coloring, vodka, and Beast Monster with a Takis garnish, served with a side of Tums. It was absolutely noxious.

this comment gave me a headache, thank you
That's actually beautiful

I don't drink alcohol and I am not irish. I am somehow offended ntl.

This is heresy

No thanks, I've no interest in jumping on the bullet train to death.

I notice the Monster says "super dry" at the top. I assume that's NOT in reference to its sugar content.

That Nitro Monster uses nitrogen gas instead of carbon dioxide for the fizzies, and it's rather dense.

Why they call it 'super dry', I don't quite know, but if you ever tried one, it sorta makes sense.
- In alcoholic drinks, it refers to a low sugar content. I figured even if this was not in America, it probably would still say "low sugar" or "sugar free" like it does here, but the other reply makes me think that isn't that case, and this DOES refer to it having a low sugar content in other parts of the world.
The ones that are sugar free specify that in big letters, so yeha it's probably the standard 9-12% sugar that most energy drinks are
