Exactly like portmanteau, only much easier to remember. Two words are
fused together by either joining a common syllable
inbredneck or by
compromising both (or possibly more) words to create an entirely new word with the combined meanings of both.
I called that rattle-trap pickup driver doing 45 in the fast lane next to
an old lady that he was an
inbredneck bastard for holding up traffic...of course I said it as I blew past him at 80 miles per hour.
Ex 2: "I heard a
rawksome band at the club last night."
Both of these are examples of a frankenword.
