The act of incrementally moving, sliding or scooting one's derrière, buttocks or rear along when sitting on a sofa or bench, usually to make room for others to sit.
Probably derived from "scoot," which means "To move or slide to the side."

A phrase meaning either "A hole dug in one location that needs to be moved to another location" or a "Loosely defined sexual activity" with the verb "schootch" essentially representing any number of things. (Meaning to be defined by context.) Ultimately, it can and should serve as a double-entendre.
Suggestion: Dig a hole in your backyard in an inappropriate location and let the double-entendres commence!
