Microblerg: Mountain Dew Flamin' Hot
At first glance, I thought it was just the current special flavor of MTN Dew, some watermelon thing. Once I parsed the logo-text Flamin' Hot, I knew I couldn't not buy it. It was disappointing, but not in the way I expected: it tasted exactly like any other orange soda, but it tickled a bit at the back of my throat. There was no perceptible heat flavor, just the throat sensation, and even that barely built on itself.
