The last yesterday, in other words, the day before yesterday.

"I'm sorry I was ill yesterday but we'll continue with what we were talking about lasterday."

Lasterday

The word you use when you are talking about something that happened in the recent past, but you can't remember the exact day (due to a black out), or it really doesn't have any significance to the story...or you just can't be bothered to think hard enough to remember it.

Amber: I just went to a Ween concert in Anaheim.
Penny: Really, when was that?
Amber: Lasterday, I think.
