The handshake that lasted almost longer than the time Sonny Bill Williams was in Sunday night's Rugby World Cup semifinal is about respecting a teammate.
Williams was filmed doing a secret handshake with fullback Israel Dagg as he ran on to the field in the last 10 minutes of the All Blacks-Wallabies match on Sunday.
Minutes later, Williams was sinbinned as a result of a shoulder charge on Wallabies first-five Quade Cooper.
The elaborate handshake - which featured a slap, a couple of knuckle-knocks, finger slides and a click - has been a hot subject on a number of social-network and news websites.
On networking site Tumblr, a person wrote: "Sonny Bill pretty much came on to show us his cool handshake and then gap."
