Taking advantage of the roommate dish-washing routine.

When your roommate has not yet washed their pot or pan, and it is still clean enough to swish water in and cook your own meal. You then leave it where you found it so they can wash it.

Only legitimate if the roommate is unaware of your use.
I've been piggybacking Sarah's pasta pot for a week, and it hasn't moved. I'm pretty sure we're just piggybacking each other at this point.
