Here are the limited edition Mountain Dew flavored Doritos out in Australia! I bought these off eBay so you don't have to! Seriously, don't. These chips are absolutely abhorrent.
The flavor starts out all fine and well. It really does taste like Mountain Dew for about a second. That first hit of flavor is sweet and citrusy. Then it happens. The remarkably repugnant, downright disgusting, outstandingly offensive off-flavor hits. It's hard to describe in actual flavor terms. It's sour and acrid. It's a flavor that should never be present in a chip or other junk food.
The flavor isn't leaving my mouth after eating one chip. Send help or a toothbrush. 2/10.
