yestersay

A statement or piece of news that everyone knows, or is out-dated. To describe such a statement as "yestersay" is like discarding it as "so yesterday".

Lisa: "Hey, did you hear that Jane Doe is dropping out of the Republican race?"

John: "Dude, that's yestersay!"

Yestercoff

Yesterday's coffee disguised as a deliciously, freshly brewed cup of coffee.

The instant you take a sip of your freshly-brewed, hot, hazelnut delight; a cold sensation hits your lips and you shriek, "DAMMIT!  CURSE YOU YESTERCOFF!!!"
