The expression is an old one that was applied to Hitler. It's still unclear if in his case he literally chewed the carpet. William Shirer used the expression in The Rise and Fall of the Third Reich.

I'm quoting Shirer:

"....And he explained that Hitler had been in such a maniacal mood over the Czechs the last few days that on more than one occasion he had lost control of himself completely, hurling himself to the floor and chewing the edge of the carpet. Hence the term ”carpet eater.” The evening before, while talking with some of the party hacks at the Dreesen, I had heard the expression applied to the Fuehrer – in whispers, of course.376"

Thanks for that history,, German shepherds and other dogs must have made the bunker a little pungent. Probably why PhotoOpObama tried to get out of the WH so much.
