Yeah right is a sarcastic phrase, two positive words, when combined, equal a negative.
In NZ, in the 1990s, the Kiwi beerTui adopted and adapted the phrase “yeah right” for a billboard campaign that poked fun at all aspects of culture, sex, romance, life and geopolitics.
“Yeah Right” became a New Zealand pop culture catchphrase and integral cornerstone of New Zealand spoken and written English. Yeah right has extensive coverage in the NZ press and went global on Youtube as the Internet expanded.
