Happy Hour incoming!

I'm the Cask Master, The Rabble Rouser,
This big man is about to blow up your trousers.
I have red hair and you say I have no soul.
But you better be aware, here's my Barrel Roll.

With the Drunken Rage I dominate you all.
I hit you hard with my big 300-pound-ball.
Never ending drink regenerating power,
Have my might back, with the Happy Hour.

Oktoberfest is founded by me.
When they see me even big boys yell "Mommy!"
My tummy is bottomless, I drink careless,
my wine is so strong it will blow you up faceless.

I can be tank, AP or AD.
You might as well look before you flame me.
You know what's corrosive, here's a simple task.
I have an explosive, catch this huge cask.

No matter how far you run after the beatdown.
I just frown, blow you out of the town.
Five of you fleeing, you feel the thrill.
I throw my cask and just hear "PENTAKILL"!

Yeah, I'm chubby as you can see,
but laugh at me and I put you down on your knees.
I can be such a ninja, rumbling closer.
You, an AP Carry, pfft... such a poser!

I'm the creator of the world's greatest ale.
It's so tough it will corrode your thornmail.
For the freshest water I head to the Freljord
You're like beer, you're best served cold.

I'm hailed as an hero, you're a little Willie
Like a real number zero you call me hillbilly.
After this showcase I head to Runeterra,
keep strong, just kiddin', I pop out your sclera.
