Inhertia

When you sleep with a gal and you really like her, it's the force (inertia) that makes it hard to leave her bed because you enjoyed being "in her."

Why are you so late to work?

I was on a date with this gal last night and I stayed over for the first time. I woke up at 7, but inhertia kept me us bed so I didn't leave until after 9. And yes, it *was* worth it.
