The act of being so incapacitated (be it from drink, or lack of sleep, or other) that you fall face-forward into a plate of food in front of you. Although the name specifically mentions pizza, it is not necessary that the food you fall into be a pizza. The messier the food the better, however, so pizza will always be the benchmark against which all other Pizza Faceplants are judged.

May be used as a noun or a verb
noun: BW was so drunk after taking the bar examination that he did a Pizza Faceplant at Basic by 7pm. No...I am serious. You would not have fucking believed it! Yes, we got pictures!

verb: Hahaha some dude just completely Pizza Faceplanted over there!
