When the cursor on a Mac computer turns into a colorful swirling beachball to show that something is loading, but then does not stop. The end result is usually having to "Force Quit" the program.
Steve: AHH!! I was just about to watch this video my friend sent me when i got the beachball of doom!

Terrence: Man, that sucks. It's not going away, is it?

Steve: Nope. Looks like I'll have to force quit Safari. Oh well...
