| v. pet·ted, pet·ting, pets |
To stroke or caress gently; pat.
v. intr. Informal
To make love by fondling and caressing.
To make love?!? Holy crap! So what the hell does HEAVY petting insinuate? Ramming? If merely petting crosses the chastity line, I think a more direct way of saying it would be "Thou Shalt Only Engage in Petting With Thine Spouse; and, If Married, Only Heavily Pet if Both Participants are Down With That Kind of Thing".
By the way, I'm actively rewriting the 10 commandments, loosely based off of George Carlin's book "When Will Jesus Bring the Porkchops?" Funny stuff. Maybe I'll just post his version instead.
