As the sanctions slapped on Russia by the Western world to stop the latter's annexation of Crimea has, on all counts, failed, Ukrainian women have now taken up the task of punishing Russia.

A 'creative' boycott has begun in Ukraine after some women came up with a new campaign called "Don't give it to a Russian" - a hilarious sex embargo against Russian men.

The campaign, which has taken the internet by a storm, seems to entail wearing a t-shirt carrying its logo: two hands clasped together, creating a shape (which men would know well!)
