The Urban Dictionary defines COMMERCIAL GAME (see below) as the game that people watch during a commercial break of the game they're actually watching.
However, when Gerald and I watch Jeopardy! in "real time", I am constantly flicking to something else during the commercials. Gerald and Les hate to watch anything with me because I am the constant channel surfer!
From The Urban Dictionary
The game I watch during a commercial break of the game I'm really watching.
"Yeah, I watched it, but it was my commercial game."
