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."

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.
