Beast-Mode 

A mode of awesomeness; A pure blank state of mind, in which you become greater (more beastly) than anything else that stands before you.

Also used when Kicking ass at black ops and someone tries to talk to you, but instead of giving them an actual convo, you just tell them "I'm in Beast-Mode right now, GET OFF MY NUTS"

When someone is constantly "Beastifying" they are in "Beast-Mode"

Bob: Dude, Jack has been in Beast-Mode for like 3 straight weeks
Will: I know, He has a 215 killstreak

Beast Mode 

From the series Beast Wars. Reverting to Beast Mode was when either Predacons or Maximals transformed into their animals forms. In Beast Mode, they were usually able to move faster and transforming also sped up their internal repairs. Also, in the first season, reverting to Beast Mode protected them from Energon poisoning, which was what happened when they were exposed to too much raw energon.

We've been transformed too long! Quickly! Revert to Beast Mode!
