Somebody who gets smashed and possibly turns violent before or after doing so. Named after Norse warriors who would get intoxicated using liquor, then fight to the death.

More modern use makes reference to people who more self-disregard and less focus on fighting or violence, and berserkers usually will do all types of drugs.

barbaric warrior that would go in to a frenzy before battle thanks to a special kind of mushroom, they would stand in front of the enemy army and taunt them. they where usually very big and strong, fight half naked (no armor) and used a big two handed axe... also they where susually the first to die, but the first to break the enemy's morale.

Get the berserking mug.
An anime show (also a manga) that combines ridiculous gore and harcore action with some rather homoerotic sequences of naked men sans genitals. the action is so harcore that most can ignore the gay stuff, or at least skip over that part.
Guts: RARRR! i just killed a hundred guys in gory and awesome ways!

This other guy with girly hair: im gonna get naked and throw water on you. and giggle.

1. A ronin or warrior mostly found in viking and some slavic cultures who pledge allegience to no master and with nothing left to loose but life itself which is often the test of their sanity and strength once the battle is done.

2. Anyone who goes balls out and gets completely lost in the moment like a maniac on a destroying mission. They are likely to damage themselves or things they should care about in the process of total destruction.

3. Anyone exhibiting insane fury and reckless savagery.

4. Dischordian element in the creative process which acts rapidly and takes no prisoners.
A beserker might be heard saying something like "Kill 'em all and let god sort 'em out."

I went berserker on his ass and I think he got the point.

We set loose the berserkers to clear the field before we sent out the couriers.

A woman who actively and agressively seeks out opportunities to display her oral sex abilities. This may also apply to other sexual advances. Her agressiveness in said area is akin to the Norse warriors from the days of yore.
That chick was a total berserker. She sucked like 50 dicks.
