A Canadian euphemism for mastrubation.
The only right way of saying it is with a Canadian accent.
Examples:
"Logan's gone again. Must be aboosin' the goose somewhere, eh?"

"I was drunkely aboosing my goose in my igloo, when I heard a scratching sound. I wondered what it was all aboot, but it was my trusty moose , so instead of aboosing the goose I went aboosing the moose with a lot of booze."
