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.
