A bizarre online cow-kissing challenge has been slammed by the Austrian government.
The #KuhKussChallenge ("Cow Kiss Challenge") was launched by a Swiss app called Castl this week.
It encouraged users to kiss cows to raise money for charity.
Castl, which has users in Switzerland and other German-speaking countries, suggested cows could be kissed "with or without tongues", the Daily Mail reported.
Austrian Agriculture Minister Elisabeth Koestinger released a statement calling the challenge a "dangerous nuisance".
