yestermorrow

Between yesterday and tomorrow; in other words, today.

We're having a party tonight, because my birthday is yestermorrow.

Yesterwear

Wearing the same clothes for a second consecutive day because you didn't make it home to change.

Hey check out Doug - he's still in yesterwear cause he crashed on the couch after everybody left the party.

YesterRia

The much more nasty and explosive cousin of the YesterDump.

I can't eat at YesterDog anymore. I can't stand this YesterRia.

yesterdecade

A portmanteau of the words "yesterday" and "decade", it is defined as the previous decade.

If the 80s was considered a yesterdecade, that makes the 90s the current decade.
