A carbonated soft drink in the UK, well known for it's humorous adverts. Originally available in orange flavour, it is now available in apple, lemon, blackcurrant, cherry, tropical, diet varieties of the above, and perhaps others.
One of the advertising campaigns which made Tango popular was a short in which a large orange man clouted Tango-drinkers around the ears. This led to a spate of copycat incidents in playgrounds around the country, and a corresponding increase in perforated eardrums. The campaign was dropped, but anyone who was broadly adolescent in the UK during the early nineties will remember.
