Webber joined his fellow Australian Daniel Ricciardo on the Spa podium, to try a unique celebration known as a 'shoey', which is basically drinking champagne from the boot they used for the race.
Even though Webber now really regrets drinking from Ricciardo's sweaty boot, he says he just wanted to join the podium finisher in the celebrations.
"So yeah. It didn't taste so great, but in the end, it's good fun. Daniel was in a moment, pumped up, full of adrenalin. I just joined his moment for him."
The bizarre Australian celebration was kickstarted by V8 supercar racer Ryal Harris, which was later followed by big time by Supercars stars such as David Reynolds.
Jack Miller then brought the 'shoey' to international motorsport at the Assen TT, then later introduced to Formula 1 by Daniel Ricciardo, when he finished second in Germany.
