: when did that (annoying) expression "hello!" (meaning to express disbelief regarding a situation or a previous statement) (sometimes used as "I mean , hello!") come into existence
: I think it is american, west coast, probably 'valley speak'
I'm guessing that the use in question originated in the late '80s or early '90s, certainly before the release of "Clueless" in 1995.
