People who have you over for a party after the normal dinner hour so they wont have to feed you. But instead feed you cake. This term is used by Italian Americans to describe "Americanos" which are non Italian Americans.
Or people who have you over for a party and regardless of the hour feed you cake instead of a home cooked meal.
aka "cake eaters"
ex. Sallys party is at 630 pm !
Thats because her familys nothing but a bunch of muncha cakes and dont know how to cook.
No its because they are cheap "Americanos" cake eaters !
