To joggle is to jostle or rhythmically shake something. The bathroom door sticks sometimes, but if you joggle the handle it'll open!
From its sound, you'd think that joggle is a combination of "jiggle" and "jog," but it actually predates jiggle by more than 300 years. When you joggle a baby on your lap, you bounce it gently, and if you find yourself nervously joggling your foot during an interview, you're shaking it. As a noun, joggle has an entirely different meaning: it's a kind of dowel or tooth used to hold bricks or stones together in a wall.
