Beowulf 

To do something extremely savage, often to further one's own personal vanity and glory. Saying "I AM BEOWULF!" also makes you epic, and is an official replacement for "THIS IS SPARTA!"

The words "gnar", "Leonidas", "Sparta" and "sav" or "savage" are synonyms for Beowulf/

Guy 1: Dude, I just Beowulf'd that guy's arm!
Guy 2: What did you do again?
Guy 1: I fucking broke it off numbnut!

Guy 1: I had such a Beowulf day today.
Guy 2: What did you do?
Guy 1: Well, I beat up five burly men at the same time, placed first in a 100k marathon, and then beguiled eight gorgeous bitches into my bed. I AM BEOWULF!
Guy 2: Umm... Okay dude. That's great.

beowulf 

(Sexual position)- When there is a man and a woman naked on a bed the man jumps on the womans back and punches her in the left side of the head until she either loses consciousness or begins to bleed profusely. This resembles the defeating of Grendall in the story.

Dude, I went Beowulf on Jennifer last night, and she has never been more pleased!

Beowulf 

Something terrible, bad, made worse, despicable, lame.
Derived from the 2007 film rendition of the "Beowulf" poem. The movie was so terrible, that the term "Beowulf" can now be applied to anything bad.

"Dude I hate that song, it's so beowulf!"
or
"That was a beowulf call, no way that was the ref is being fair!"

Beowulf 

The first book written an English language (in this case, Anglo-Saxon), it is probably the most boring peace of literature to have ever tortured English students.

Sorry that I didn't finish Beowulf, it was more fun watching paint dry while I was stabing myself in the aorta.

Beowulf 

Boring book they make you read at school, describing some hero called Beowulf killing a demon. Nobody except English majors really care about it.

Beowulf was a hero. He does hero stuff. He makes a point of being a dick about it. Beowulf is cool.
