Meameamealokkapoowa oompa

The meameamealokkapoowa oompa is equal to $$\{LLL \ldots A \ldots LLL,10\}_{10,10}$$ in BEAF, where A is a meameamealokkapoowa array of L's. . John Spencer first asked for the definition of this number.

It is celebrated as the largest googologism Jonathan Bowers has yet defined, and is possibly the largest named number. Rayo's number might surpass it, but it is difficult (if not impossible) to compare the two, since they are defined in very different ways.
