I actually tried the Black Ice flavor a few days ago. It pretty much just tastes like an energy drink in the realm of Rockstar (I've never actually tried regular Monster, so maybe it tastes like that?). If you let it melt, it's kind of gross. I recommend putting a small layer of it at the bottom of your Slurpee, like 1/2" to 1", and then throwing some more reliable favorites on top. It works out pretty well. There are Dr. Pepper Vanilla Slurpees somewhere?! Where are these?!

Here's a legit question: Why does Canada get all the best Slurpee flavors? Why do we get this crap sugar-free Crystal Light nonsense instead?!
