A Saltine Cracker is a term for the Devil. A Saltine Cracker is White and is loaded with Salt... Ergo: Salt = "Meth", Cracker = "White Person", so when you put them together: Saltine Cracker = "Satan", as Satan uses Meth to brainwash all you honkeys!
As a command: Shut up Saltine Cracker. I told you before "GET OUT of My House, and leave them humans ALONE".
As a comment: "Mom, I don't like Saltine Crackers. You always give them to me with Chicken Noodle Soup, and it reminds me of being SICK!"
A dare where you have to eat 6 saltine crackers in 60 seconds without drinking anything, and all the crumbs must be eaten as well. Although it sounds easy, it's actually really hard because the salt and crumbs dry out your mouth and are hard to swallow and you can't drink anything to help you out.
