Meameamealokkapoowa oompa

Meameamealokkapoowa oompa is equal to \(\{\{L100,10\}_{10,10}\text{&}L,10\}_{10,10}\) in BEAF, or a meameamealokkapoowa-sized array of L's. John Spencer was the first to ask for the definition of this number.

For years it was considered the largest googologism Jonathan Bowers has yet defined. It was conceptually superseded by Utter Oblivion in 2016 but only conceptually for Utter Oblivion is not a formally defined number. Howsoever a meameamealokkapoowa oompa is to be defined, it is certainly smaller than Rayo's number, and is also believed to be beaten by Loader's number. The exact size of this number is controversial, due to not having a proper definition. Some estimates have put it as much larger than \(f_{\psi(\psi_I(0))}(10)\), whilst other analyses put it only slightly larger than the Large Veblen ordinal; less than \(f_{\theta(\Omega^\Omega+\Omega)+1}(10)\).[citation needed]

It is most likely pronounced like so:
