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

I'll pass on the Billie Irish.

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.

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

This is what Brexit did to Ireland.

Where my hydro homies at in these times of need?

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

How is monster denser than Guiness...

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

Liver failure.

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

What a terrible thing to do to a Guinness

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.

It must taste like sadness

Okay That's seriously looks like a radioactive diarrhea.

Irish gut bomb.

Is this legal?

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

Ass.

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.

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.
