I remember when I was in high school, one of the gym teachers admonishing a class about public displays of affection, using the phrase "playing huggy bear kissy face". (Don't remember which teacher, oddly - maybe Mrs. Casey, Miss Provost or Mr. Hill.) I doubt the phrase originated with that teacher, or even in that school, because if you Google the exact phrase "huggy bear kissy face" now, it returns about 13,400 results.
