The sometimes-seen-as-sexual way in which Winston Marshall (nicknamed Win-Dogge) of Mumford & Sons sways forward and back, leading with his hips, while playing his signature banjo riffs. Can be seen in live performances of "The Cave", "Roll Away Your Stone", "Little Lion Man", and ""Lover of the Light" most commonly.
Also seen in the band's music video for "Little Lion Man".
