on, fantastically on, the opposite of off, bringing it, go time, It's so seriously on...as in if you google "on", donkey kong would pop up...or if you google fought donkey kong and off...donkey kong, by a land freaking slide.
Example 1:
Someone challenging your epicness:
Let's play.
You:
What? Let's play? It's on like Donkey Kong.
