Beast Mode

Partially derived from the sports world (Marshawn Lynch going beast mode in the NFL). It is when you are super busy and have deadlines. You put on earplugs/headphones and drink caffeine in an attempt to knock out work/coding.

Did you see Rohan? He went beast mode on that compiler program today and finished it on time.
Man! Andrew went beastmode on my escalated technical cases today. Awesome!
