Every other language has a word for the day after tomorrow, and it gets super annoying to keep saying such a long saying for such a useful term. The day before yesterday is similar, but it isn't defined in may other languages.

This is why I suggest we make finally make words for these two common phrases.

I suggest we use 'postreed' [poh-stree-d] for the day after tomorrow and 'disentri' [Dee-sen-tree] for the day before yesterday. This is because in Latin, the day after tomorrow is 'postridie' and the day before yesterday is 'Dies ante heri', and most of the English language is based on Latin.
