all_your_base_are_belong_to_us_(meme)
A meme resulting from a shoddy English translation of the video game Zero Wing by Toaplan.
The correct translation is supposed to be "With the cooperation of Federation Forces, CATS (zero wing) has taken over all of your bases." (JP: 連邦政府軍のご協力により、君達の基地は、全てCATSがいただいた).
