A poptart without frosting/icing.
A yeam is gross. Poptarts need icing/frosting.

A quantity of 15. It can be used in the same context as the word "dozen." However, unlike a dozen, a baker's yeam is 14 so the baked goods will be easier to fit in a box. Also, since 15 is an odd number, a half yeam is rounded up to 8.
I'd like a yeam of potatoes from the store.
