Done that way too many times. It's just habit. I'll do it when I hop into the car when wearing jeans or shorts.

Nah, when you do the pleat sweep, you're keeping the pleats straight when you sit down on a chair, bar stool, etc... Sometimes it is easier, however to just plop on a bar stool without having the pleats underneath. At that point, make sure that the skivvies are clean.
