back in the day 

As in yesterday. Ironic usage of an older expression. Making reference to our collective short term memory. The constant churning of events from the present into the bin of discarded Time magazines.

Back in the day there was a future that is now old news.

Back In the Day, we had no way to check in, or be checked on if we were outside, or away from a landline phone.

Back in the Day 

A time in which none of the currently occurring negative events could ever have taken place. No matter what the current circumstances are, you can rest assured that back in the Day, they never would have happened. Even if it seems likely that they would, some type of Deus Ex Machina event would have occurred that would most certainly have prevented the current situation from happening.

"Back in the Day, you could have jumped off of those Cliffs and still Swam for the Olympics the following Thursday".

Back In the Day. 

Regarding a time before you mattered. A time that you were not a part of. You must have at least 5 plus years on to even say this phrase.

Back in the day I didn't even work here because I don't matter and should never say back in the day.
