Should there be, or is there, language for motion graphics?

I didn’t ever go to school for this or anything but when I’m on phone with clients discussing how they want something to animate, it can often be hard. It’s not easy to describe how complicated motion graphics movements could or should flow. Easy to understand with visual aids, or when meeting with client or designer in person, but not long-distance, by phone or in MSN Messenger/ Gmail chat etc. any thoughts?
