After reading Pat's entry about his triangular exercise plan, I confess to not having the slightest idea what a "dip" is and only a vague notion of a "crunch," only that they probably involve preparing to go shirtless in public, something I am not willing to do.
When we were boys, my brother and I would insult each other by calling the other a "dip," which was short for the fantastically defamatory "dipwad." We would do it over and over again until mom would get fed up and call us both "turkeys" and tell us to shut up.
