What does bah mean in Latin?

Answer 1

If you're asking "What does the Latin word 'bah' mean?", then the answer would be nothing, since it's not a Latin word. But, if you're asking what, e.g., an ancient Roman would say instead of "bah" (as in "Bah humbug!"), then there are a few options, but I don't know them. However, if a Roman swore, he might say mehercule!, meaning "By Hercules!", but this is kind of like saying "My god!", so it may not entirely be correct.
