Mbo,

"Inundate" an NCism? I don't know how long I've known the word, but you can bet it's in the vernacular of most literate people who live close to a large body of water. It certainly is around the Great Lakes and along most sea coasts.

As for the others, they may just be regionalisms and you can find equivalents everywhere you go.

One of my favorite memories of a difficuly caused by them was watching and Air Force mate of mine from Boston getting slapped by a waitress in an Oklahoma City restaurant when he asked her for a frappe. She later told him she had no idea what it meant, but it sounded dirty.

cheers
