Saying you're down to do something means the same thing as saying you're up for it.

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
In my friend circle we will invite each other to stuff and ask "are you up or down?" Then schedule them regardless of response.
