Oldfangled is the New Newfangled

Is there a word for this sort of word? A word- like "NEWFANGLED" that seems to imply an ironic "OLD-FANGLEDNESS". (Seems the sort of word only uttered by 90 year edentulous old-timers between other phrases like : "Dagnabbit!"*, and "Darn Tootin'!").

*Urban Dictionary defines "Dagnabbit" as:

An expression of sheepishness, with a tinge of frustration.

e.g. "Dagnabbit, I knew I shouldn't have put my tongue in her arse on the first date. Now she thinks I'm a freak."

This is very funny.
