I beg your pardon; I made a rare typographical error. The expression is "zoom dweebie." I would define it as a person who is exceptionally exasperating in some way, on a consistent basis. It has no relation to the current term "dweeb;" "zoom dweebie" was in widespread use forty years ago.

In fact, I suspect that "dweeb" can probably be traced, etymologically speaking, to "zoom dweebie," although the meanings are different. Kinda like what's happened to "gay."

There is only one slang word (an adjective) I know of that has maintained its precise meaning throughout many decades: it is used by teenagers today exactly as it was by teenagers fifty years ago. (It's not dirty.) Can you guess what it is?
