Difference between MPT and NPT threads?

Trying to sort out plumbing acronyms, and someone isn't helping:

I still dont understand because I have NEVER seen a pipe with either a penis or a vagina. Have you?    <lol> 
(I did see several pipes that had nipples though, so I instantly knew they were female) !!!!!!!!!!!!    :)
Just to confuse things. MPT is a subset of NPT. Because NPT can be MPT or FPT. So, they aren't totally interchangable. Not to be a PIA, cause a MPT would go nicely into a same size FPT, but can't guarantee that a MPT would go into a NPT, only if it's a FPT NPT. If it were a MPT NPT, that wouldn't work. So, if you have a NPT FPT on your SUV, you need a MPT NPT, or you'll be SOL. KWIM? Then, you'll need a BFG, or  BFH.
