Same as the blockbuster swap, the blockbuster switch off is when one becomes tired of their old DVD or game due to scratches or cracks. The basic idea is to rent the same DVD or game and return the older copy in the case. When replaced with a disc different than the one intended to be kept, this becomes a cluster fuck.
I'm getting tired of my PS2 not reading this disc, Sal. I think we're gonna need to pull a blockbuster switch off.
