To devour (as in food); to complete something in its entirety and whoop its ass.
"Man, I was so hungry earlier that I totally beasted out on an entire pizza."

Get the mug
Get a beast out mug for your friend Rihanna.
The always manly over exaggeration of a night's events...often there are no witnesses to back up said beasting out. People who tell fictitious beast out stories must always be called out.
when asked what a friend did last night, friend replies with beast out: "I shot-gunned 14 beers, but I was cool to drive. I hopped in my wrangler and said fuck roads...I drove through the protected indian reserve while tripping on the acid I just had taken. After I evaded the feds I went to my friends house she had a friend over, we had a three-some, no biggie, typical wednesday."
