Very reminiscent of the All Blacks from NZ before the match psych up still funny
Psych up? i suppose that would be naturally part of it...however its more like this...

hey bro, stand by, coz we is gonna smash you six ways of sunday, / come get some if you think your hard enough...

I LOVE that commercial! Brilliant!! If you don't know about the New Zealand "All Blacks" rugby tradition, search YouTube for "Haka" to see where the idea came from. There are some GREAT Hakas to be seen!
I particularly like this one because the Tongans respond with their own war chant:
look for samoa and tonga, the most impressive by far...

instead of doing it an injustice, please follow the link...

playing ruggers in a kilt, man that would not be cool, there is a fine tradition down here, that is deeply ingrained in the game, which unfortunately the world stage has slowly removed, but is still conducted every sat during winter;
Rucking, the fine art form of destroying the opposition for putting their hands or body on or blocking the ball. wearing a kilt and getting rucked, oh so bad an idea.
when i was a kid we had plenty of people that needed new jersey's after games due to some "revenge rucking" for a big hit or try etc etc...
