when someone says i work under neath him not biblically of course.. what does that mean. (not biblically...)?

I think it refers to the missionary position. You know: the nasty, mystery dance, beast with two backs etc...

Usually when people throw the "biblically" bit in there it refers to sex.

To detail previous answers - he is your immediate supervisor (boss). There is most likely someone else to go to for help, but he would prefer you to just ask him. Ego boost for him maybe?

Naw. That's just speculation on my part. Although usually when that phrase is used, I tend to raise an eyebrow because the boss-type saying it is an *** of the highest degree...

What are you really asking, if you are saying not biblical? Underneath as in you have someone in a higher position to answer to would be my answer.

underneath as in "him" is a boss or manager or higher being. or that the person literally works under..prostitution? :/

That means he is your boss.

means that he's the boss of you

you are subordinate/ you answer to that person in a work environment.
