Pinception 

Where you find yourself lost in Pinterest after chasing the rabbit down the 'more like this' path and lose sense of which layer of pins you're in.

Crap, I can't remember how deep I went. Was it a pin within a pin? Or a pin within a pin within a pin? Pinception!

Playception 

The play-within-a-play part of Hamlet. Or any other play, for that matter. Can also mean TVception, when you're watching a show/movie in which you spend a small amount of time watching what the character's watching.

"The Reduced Shakespeare Company needs to add in something about playception; Hamlet needs more pop culture if they're going to Abridge it!"

"In the cartoon I was watching, we spent five minutes flashbacking to the main villain's childhood cartoon! Playception at it's finest."

Penception 

When you are drawing a line within a line within a line, and the line then takes on a life of its own. Eventually the line will be taking YOU for a walk. And then you realize that you are in Penception.

The term became popular with the release of the procedural drawing app "Penception" which makes use of algorithms to interpolate your next line, based on the lines that you have already drawn.

You are in Penception.
