Ni!
Knights say “Ni!”. Knights eat hobbits. Raw.
Especially in this case - since a Hobbit hole is one of comfort - Not a nasty, dirty, wet hole, filled with the ends of worms and an oozy smell, nor yet a dry, bare, sandy hole with nothing in it to sit down on or to eat.
If they were, indeed, referring to a Hobbit Hole, I would say “Thank you sir, and Good Morning”.
An orc hole, on the other hand…
Check it for treasure and get the hell out of there…
Without reading any of the other responses, my first thought when I saw this insult was “Oh, this guy thinks I’m a bug. Because bugs live in holes.”
What are you saying about my mother?
I always interpreted it as a hole in the ground, but yeah vagina makes sense too.
Doesn’t really matter though, the person doesn’t like you either way.
That her hole is so big as to require a door, and possibly a revolving one at that?
(j/k of course, I neither know yo momma nor have I visited her hole)
Like a revolving garage door.
The expression in general refers to a hole like a dark burrow or cave, implying the subject is like a rat, insect, or troll that is unfit for human company.
I’ve never heard the exact wording reported in the OP, though. My first thought would be that the person saying the comment misspoke or misheard the expression originally. If the speaker is deliberately trying to tweak the expression to make it a more vulgar reference to a vagina … I’d roll my eyes because it’s not nearly as clever as the speaker probably thinks.
“help me find my keys, we’ll drive out of here”
Not necessarily… it’s also meant to indicate an uninformed person. As in, “go back to your cave where you’re disconnected from everyday life.”
