There is no question that there is a Rugby version of this song. Traditionally, a new player is forced to perform the dance in the bar after they scored their first try (touchdown) for the team.

The meaning of "Take em down.." is to take down your pants. And like the gentleman from Canada points out, the result is to get completely naked and fall off of the bar into the crowd.

I scored my first try so long ago, I can't remember if I performed this or not. I don't care what the pictures look like.
