hmmm do second order acronyms, acronyms of sentences that contain acronyms themselves, use the original acronym or do they instead use just the first letter of the acronym?

I assume that it would be just the acronym itself. so the phrase "Built for BBC" would become "BFBBC". But then you wouldn't be able to differentiate a second order acronym from a third, fourth or nth order one. They would all look identical. But then what about the other option? Say you turn "BBC" into an acronym using the first letter "B" (it kind of sucks that her new partner has a bigger dick than me, but I mean its to be expected height does correlate with dick size, and its fine no really, we were pretty much just using each other in the end anyways) Then the second order acronym would be "BFB" but that also loses a lot of information, I think the latter is much worse.

Do you guys have any ideas this is very important for those of us in the "buzz word" community which for whatever reason includes both ends of the extremist wings of the sociopolitical delimination.
