I wasn't thinking of what kind of slang she used, but now that you mention it, that could explain his confusion.
I saw it another way; in Florida we have people so old that they predate the World's Oldest Profession.

No it wasn't.
1) Not nearly that old.
2) Don't pick up anyone, especially not hookers. (Not really a fan.)
just messin' Gramps
