Palindr-antonym?

Huh?  OK, confession.  Sometimes when I can’t make up my mind I make up a word.  Help me out here.

A palindrome is a word, phrase or sentence that ‘reads’ the same backward or forward. They can be simple like ‘race car’ or ‘deed’ or ‘madam.’ Or, more complex, like ‘A man, a plan, a canal, Panama!’

An antonym  is a word opposite in meaning to another, like ‘fast’ and ‘slow.’

Which is this?  (Watch it all the way to the end before you decide.)

Whatever you decide to call it, I bet you’ll call it ‘amazing.’
