Hahaha I'm down means...

I'm in, I'm game, I'm up for it, I'm excited about doing that, I'm willing, I'm into pursuing that idea, etc.

It can also mean I am cool with or understand a concept, or I am associated with a group of people.
"hey. I'm about to go skate in an abandoned mall! You in?"
"That sounds sweet. I'm totally down."
Or

"oh! Microbiology? Yeah, I'm down with that."
