Yestermorrow

When you can't remember what day something happened, because you've been awake for too many consecutive days.

Person 1: Remember that party yesterday... wait, or was that this morning?

Person 2: I don't even remember anymore, it was yestermorrow.

I wasn't born yesterday

Something you say in order to tell someone that you are not stupid and are not easily deceived.

Mom: Timmy, what was that sound?
Timmy: Idk mom, it was probably Johnny masturbating again.
Mom: I wasn't born yesterday. Get your damn girlfriend out of your room.

yesteryear

Years ago, not last year, as you would assume from the meaning of 'yesterday'. it's much more general. Middle English, not really in use nowadays.

I think back to my golden memories of yesteryear...
