You are correct, "Slurpee" is the brand name of a slushie (frozen carbonated drink) that is sold in 7-Eleven convenience stores around the world. These drinks are self-serve, so you can make diverse flavor combinations for your Slurpee. Ex: It's so hot out, wanna get some Slurpees from 7-Eleven? Ex: My Slurpee is so cold, it gave me brain freeze.
