To consume some type of food or medication in order to unclog a constipated keester such as coffee, prune juice or a greasey steak sandwich.

That correctol I slipped into grandpa's prune juice was just what the docta ordered for greasing the skids! Now he has skid marks that could make all the residents of Shartlesville envioius.
