Kseniya Ryzhova and Tatyana Firova were two of the Russian team who won the 4x400m relay in Moscow. When on the podium receiving their medals they kissed, on the lips. It is being taken in Russia as a protest against the anti-gay laws and has kicked up quite a fuss.
Good for them.
Edited: I think it's important to point out that if this is in fact a protest then these women could very well have ended their careers with this decision. Russia is not low on talent when it comes to athletics and they are well known for black-listing when it comes to any kind of dissent from athletes.
