"Biblically drunk" is the kind of concept you get when (A) you live in an isolated compound completely cut off from the real world, and (B) within that isolated compound there is a (literally) century-long tradition of obscene overdrinking that is informally condoned, so long as it is not an overt embarrassment (e.g., "well sure, he drank a whole bottle of Jack Daniels in less than an hour, but he walked back to his room under his own power without falling down or puking so he must not have been Biblically drunk").
