Four zeroes, go!!

When cheap digital egg-timer finishes its countdown, it looks like this: 00:00

Basically an alternate end to a countdown from "3...2...1...0, blast off!/go!"

Term originates from the Pokemon theme song when played backwards. You can find this on youtube.

"Really she's my maid, she's real cool, so.... four, zeroes go!"

"5...4...3...2...1...Four zeroes, go!!" *launches rocket*

Go Zero

To be forced operate with efficiency, without being swayed by emotion or external factor. Objective completion with swift calculated action under duress, while remaining unemotionally confident.

There was just so much going on and all of the sudden I go zero and it was all done in minutes.
