iBubble 

A term used to describe the state which one enters when turning the volume up on one's iPod, rendering them oblivious to the world around them.

Basically you can't hear anything so you're in your own little bubble.

Term coined by Nicole Scribner

Jake was in his iBubble again so I grabbed his iPod and pulled out the headphones so he would listen to me.
