when one gets caught up into the process of eating and at the end of it forgets how much one ate.
Dude i had food blackout once I ate like 3 hot pockets, family size bag of Doritos, a oven pizza, and went to Mcdonalds in the past hour.
A state of mind where a person is completely unaware of his or her surrounding, because he or she is too busy eating something insanely delicious.
When waking up from food blackout, you will often realize that you have been eating like a complete pig for several minutes, but despite of having dusins of people starring at you with disgusted looks, you are mostly just sad that a large ammount of the food you were eating is now gone.
Person A: "Dude, you´re like half way through your meal, and I havent even gotten my food yet!"
Person B: "OM NOM NOM!"
Person A: "DUDE!!!"
Person B: "What!?! Oh, Sorry I had food blackout."
