All I know is that one of the best reactions I ever got from showing off, was when a few chicks were talking about an old TV commercial where they said "if you can pinch more than an inch, you need to lose weight". I carefully reached under my shirt, and grabbed one of my abs, like it was a roll of fat, and lifted my shirt up just enough to show the pinched ab in my fingers.... I said to the girls, "I guess you mean I need to lose weight, because this looks like more than an inch to me". They looked, and thought I was just being honest. Then I lifted my shirt the rest of the way, and their jaws dropped when they saw that I was grabbing a muscle, with paper-thin skin over it!
