Kiwi shoppers have the foulest mouths when rating products online, a global survey has found.
New Zealanders are quick to rubbish high-tech gadgets like laptops and tablets as being "crap".
Since the start of last year, 1.61 per cent of reviews from New Zealand on international social commenting platform Reevoo were rejected for swearing, ahead of Russia at 1.06 per cent.
A typical Kiwi example, Reevoo said, was: "Windows 8! Crap!''

The study also found that Romanian, Czech and Russian-speaking people tended to swear more than English, French and Spanish speakers.
Consumers in Finland and Japan wrote the cleanest reviews.
Reevoo said of the 1.5 million selected reviews from 90 countries, the most colourful language was reserved for describing mobile phones, laptops, tablets and travel services.
"It's as much down to consumer passion as opposed to products themselves," founder of Reevoo, Richard Anson told the New York Daily News.
