A base established on a moon. In particular, the two bases established by the Autobots on the two moons of Cybertron prior to Transformers: The Movie. Given the highly original names "Moonbase One" and "Moonbase Two" (!!), these were to be the base of operations for recapturing Cybertron from the Decepticons. They were meant to be secret, but the Decepticon Laserbeak was able to infiltrate them. Before any attack could be launched, the moons were devoured by Unicron.
Jazz: "Some ginormous planet-looking thing has just showed up in the suburbs of Cybertron"

Bumblebee: "And it's attacking Moonbase 1!"

you see someone 'visually pleasing' walking down the road-and if youre feeling bold you can either shout 'moonbase' in their direction or say to someone 'oh! i was walking down the road and i saw a proper moonbase' provided they know what it means.
the phrase originated on the south coast of england.
(very hot man walks toward you)

'moonbase !!' you shout.
