Hi Not me,
Not sure here but, I have always known BAC as meaning Born Again Christian? Yes, I am also confused with the "cats" and "Elijah" lol.
born again christian, by any chance, either way you either got a cat or you dont i guess, right, "bac" is irrelevant to the concept being communicated iow? But he has no cats apparently.
so, "leave some for Elijah" is...ha, a thing Jewish ppl say, google could prolly splain that better too i guess, dunno...ha, ya, dunno what your Gsearch of "leave some for Elijah" with quotes returns, and i cant import mine here bc ipad, but you can maybe get a sense of what is meant by the phrase if you read between the nonsense maybe.
I thought it was a more or less cliche even among Christians, sorry. Something like...ya, i dont even want to muddy the pool there lol, obv Jews are still waiting for Elijah, so just a slangy way to say "for later" with certain undertones. Doesnt really matter, i'm strictly fodder for the cannon here anyway, should be pretty obv by now i guess; "the rest" has now been completely buried and forgotten, right, nevermind the rest, what rest lol
