This guy's girlfriend wanted to make a special meal for her significant other. Perhaps it was their anniversary or some other special type of date, yet she managed to make a complete mess out of it. Luckily her boyfriend has a sense of humor. What appears to have happened to the mac and cheese is that the meal got burned AND dehydrated - meaning it stayed in the pot for too long.
The taste must have been terrible. In fact, if these two have any pets, there is a pretty big chance that their pets would never attempt to eat this thing... if the pets could speak, they wouldn't even call this food. From some angles, it looks like some kind of weird, boiled brainy type of tissue, which is a horrible thing to think about.
