do you remember when you first heard it and what your reaction was to it at the time? On the TV show Full House. The dumb neighbor's even dumberer boyfriend would say "Whatever" in response to almost anything. Did I mention he was dumb?
(Wasn't Dumb and Dumberer the title of a movie?)

And, I can certainly see where a constant totally suberb could get annoying! (I expect to see/hear a Dude follow it, as in totally suberb, Dude.)
