Nostalgia Ninja

Something from the past you never knew knew existed, but realize as an adult you know everything about them.

Air Supply? Never heard of them. Oh, yeah, I recognize that song. Hey, I know all the words to this one. Wait, I know that one too. Holy crap, they also sang this one?! How do I know all the words of 11 of their songs and never knew who the hell they were?!?! That snuck up on me like a nostalgia ninja!

Fat Ninja

The unsubtle affair. Where two people think they are being sneaky, but everyone knows what is going on.

The act of cheating out in the open, but being oblivious to it.

Joe: "Do Bill and Sue really think no one knows they are hooking up?"

Bob: "I know, right? Pretty Fat Ninja there."
