What do you call it?
If "other," what do you call it?
[Edit: I didn't mean to cause a great battle against "pop corn" and "popcorn," but that seems to have happened. For the purposes of my poll, "pop corn" and "popcorn" are the same, but I realized that in real life that's not the case. So if you wish "popcorn" (no space) was one of the choices, go ahead and choose "other" and write it in. Everyone else is.]
