Multi-use term that describes using the butt of a male or female as a medium for therapeutic purposes.
John: Last night I was feeling blue so Margaret let me fondle her butt, followed by a good face to ass session, ending with anal penetration. It was complete butt therapy.

Margaret: After a long day of work, I let John use my ass for multiple hours in different ways. It’s my daily dose of butt therapy.
