"All your base are belong to us" (often shortened to "All Your Base", "AYBABTU", or simply "AYB") is a broken English phrase (see Engrish) that sparked an Internet phenomenon in 2001 and 2002, with the spread of a Flash animation that depicted the slogan. The text is taken from the opening cut scene of the European Sega Mega Drive version of Zero Wing, a Japanese video game by Toaplan.
