Watch Alicia Vikander Demonstrate Sweden's Sexy Frog Dance

Summer's hottest dance move!

Alicia Vikander is making the rounds to promote her newest movie, "The Man from U.N.C.L.E." -- but last night (August 13), she had a much more important job to do: Teaching us all the hottest summer dance move from her native Sweden.

The dance is called "Små grodorna," which translates to "The Little Frogs," and yes, there's a song to go with it.

We don't think it's too soon to declare that the Swedish frog hop is the hottest dance craze of the summer, or maybe even of all time. Master it now and astound your friends.
