Sonic Drive-In Red Bull Slush

I know I ordered a Red Bull Slush at Sonic Drive-In but I'm not sure that was what they got me. It didn't taste like Red Bull and wasn't red. Then I haven't had Red Bull since it came out so I don't know.

Stuff gave me a brain freeze right off. If you're looking for super cold this is good. If you want to get pumped up this didn't do that much for me.
