Speaking of expression derived from TV media...there's the word "Grok". Some of us been using for it so long that it's been second nature, but for those under-45 ... or those not brought up around certain college or urban areas, they may have no understanding. They don't grok it! I had to look up it's derivation...that it came from Heinlein's 1961 book, 'Stranger in a Strange Land'. Taken from the novel:
“ Grok means to understand so thoroughly that the observer becomes a part of the observed"to merge, blend, intermarry, lose identity in group experience. It means almost everything that we mean by religion, philosophy, and science"and it means as little to us (because of our Earthly assumptions) as color means to a blind man. " He used it as a Martian word which started out as meaning to drink.

Aresnio's 'Whoop whoop'..had to have the whirling forearm along with the cheer. His Arsenio Hall show was where it generated from. Very '91-'92-ish.
Oh yeah...Have a Nice Day. We used to use "HANDI", which translated to Have a Nice Day, Idiot!
