When you pop some bread in the toaster, you make that sad feeling of NOT having any toast...toast! See what I did there? I think that's what you call an idiom. Or a homonym! Or a snackamajig! Words! They're great!
Now, about that Toast! Toast is a simple snack to accompany coffee, tea, or a collection of decorative pillows! White or wheat, it can't be beat! Hooray Toast! 18 inches of all new polyester fiber (and 7 inches thick), ages 3 and up only!
