Mouse back 

A frozen mouse in a glass of milk, drank on the side with scotch and tomato juice, jeffery dahmer’s specialty cocktail.

Darwin was sick from the mouse back, but he knew he had to finish it, for it was dahmer’s favorite, for the homies he said. And then passed away.

Backseat Mouse 

Like backseat driving , telling somewhere what to do and how to do it while on the computer. Can be very annoying.

Chris: And you're gonna click over there, then-No no no! Click right there!!

Paul: Man, stop backseat mousing me, I know what to do.

Lindsay: John is so controlling!

Bill: We all know it, whenever I'm on the computer, he backseat mouses me all the time, he needs to chill!
