because day after tomorrow is just too many syllables

Poplollies and Bellibones is a fun book by Susan Kelz Sperling about words that have fallen out of use in modern English. I found a copy for a dime a few years ago at a book sale and have been enjoying finding and trying out new (old) words.
I am on a quest to bring overmorrow back to common usage.
It indicates the day after tomorrow and has a commonly used equivalent in German, Dutch, Swedish, Norwegian, Afrikaans and French.
Come on people, join me in promoting overmorrow in sentences such as, "Overmorrow is Saturday; let's go dancing" and, "There is no possible way i can have 70 original greeting cards created by overmorrow! Have you gone insane?"
