look up any word, like sex:
When two or more people use each other for sex. It is considered ok, because all of the parties consent to being used and in turn use the other parties involved. There are no feelings involved in mutual usage; it's just for kicks.
I slept with Arnold last night, and he didn't call me today. It's ok, though. I was using him too. It was totally mutual usage!
