New Zealand's national rugby team, the All Blacks, beat England 26–7 in the Hong Kong Sevens tournament on Sunday, but all those details are kind of irrelevant. Wht happened after the match is the important thing.
Despite (or perhaps because of) the rain, the victors stripped off their shirts and performed the traditional Māori haka dance. The dance is performed by the All Blacks prior to a match, with the aim of intimidating their opponents. But they decided to give it another go afterward for the sole purpose of titillating you—or, celebrating their win. One or the other.
Does it matter why?
