what is that little hand held tool that i've seen in music videos and the like where they hold it up in front of the persons face and click the button?

Sounds like you're talking about a light meter.

I use one every time I go out with my cameras, mine will do still and video

I'm going with 'light meter' as well. A device used for measuring the amount of light in a scene, and from that, helping you determine your exposure settings.
