Older users of this site may recall the 'Bill & Ted' 'Wayne's World' series of movies of the early 1990s. They were mindless but fairly amusing and their eponymous characters spoke in a unique vernacular, part-stoner, part-surfer, part-moronic generation MTVer. One of the features of this sub-language was the use of the word 'Not' usually written as (NOT), a convention which served to negate the content or validity of what had been said previously.
E.g.
"I think your wife is very attractive. (NOT)"
or
"I love your new hairstyle. (NOT)"
Does anyone know if this usage is a modern invention or whether there are antecedents in ancient or more recent languages which are similarly employed to, wittily or otherwise, invalidate previous statements spoken? I'm not necessarily looking for usages of 'not' itself, but any similar linguistic devices.
