Based on a 1989 Japanese video game, the phrase "All Your Base Are Belong To Us" has spread the internet with high velocity in the early years of the new millennium. The game called Zero Wing (Copyright Toaplan) was translated so poorly that the Engrish used in the game quickly became an internet meme.
A Flash movie was created depicting several uses of the previously named sentence, sometimes shortened as AYBABTU and a Canadian group called "The Laziest Men on Mars" even created a music video with numerous photographs (some clearly digitally altered to include the sentence "All Your Base Are Belong To Us") flashing by to the beat of gabber music accompanied by 'voices' of characters from the game.
