meet my goose

The act of pinching someone's buttocks (either playfully or as a way to get them to move out of your way), as though a real goose was grabbing a beak-ful of flesh. You can do this with either your bare hand or a reaching stick (assistive device used for picking things off the floor when you can't bend at the waist).

They just discharged me from the hospital and I needed a wheelchair to get to the car. Some idiot walked in front of me and wouldn't acknowledge me when I called out, "excuse me", so I made them meet my goose with my reaching stick. They took the hint.
