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*
