It's American Football, played by women in their smalls. And it's coming to Dublin.
You may or may not be familiar with the Legends Football League, but you might know it under the name of 'Lingerie Football' (they rebranded a while back, possibly because of criticism of the fact that is was, well, girls in their pants getting muddy.
It's not strictly lingerie any more, as along with a new name the sport also introduced a (slightly) more conservative uniform, but we feel the old name and associations will be hard to shake.
Established in 2003 as an alternative to the Super Bowl half-time show, the sport is a full contact, seven-a-side league with franchises in the US, Australia and Canada.
And now it's coming to Europe, with tryouts to be held in Dublin and Dusseldorf soon after it was Manchester's turn last month.
“This is certainly an exciting time to be part of the LFL and a fan as the sport continues its unprecedented growth globally," said LFL boss Mitchell S. Mortaza in a statement on its website.
"It’s amazing to think that women from places like Germany, Italy, Russia and other places all over the world are aware of our sport and aspire to play on the now global stage of LFL Football."
These girls can hit hard:
Here's a useful educational video. You will need "athleticism, lingerie and a helmet".
The plan is to have a UK, Irish and German franchise in the sport by 2014, Mortaza said.
Details for the Dublin tryouts will be announced "within two weeks".
In the US, team names in include Las Vegas Sin, Minnesota Valkyrie, Los Angeles Temptation and Philadelphia Passion.
Over here, fans will have the opportunity to vote for the name of their national team.
So what do you think it should be called?
