I don't really get (or care about) the video gamer connection here, but blackberry lime Slurpees sound pretty darn good. I wonder if Sonic has blackberry limeade?
The Impulsive Buy also reviews another weird beverage: Butterscotch Krimpet Cupo'ccino. I used to work with a woman from Philly, and she brought Tastykakes in to work from time to time. It was the first time I'd even heard of them.
