fallout effect 

Having great urge to do something, preferably video game related (fallout 3/ fallout new Vegas), and once the activity is about to begin, you lose all urge to do said activity.

"I'm going to go play fallout 3" *loads up fallout* "I don't want to do this anymore"

"Why not"

"I got the Fallout effect"

The Fallout effect 

Listening to a song over and over so much you start to love it

Jerry: You know Jackson's listening to Ella Fitzgerald now?
Johnny: That's The Fallout effect for ya
