This clip comes from Plants vs. Zombies, the tower defense game released by PopCap in 2009. The announcer-style line plays at the start of gameplay and became memorable because of the game's catchy presentation and distinct voice cues. Online, creators reuse it as a funny start signal for streams, challenge videos and game edits. It still works well because even people who have not played the game understand the meaning right away: something is about to begin.
