look up any word, like donkey punch:

2.
A word that Justin has added to the dictionary in order to (1) prove Alex wrong and (2)continue using it without further looking stupid.
Alex: Misconsumption is not a word.
Justin: Yes it is. It is the action of consuming something in an improper manner, such as: 'The misconsumption of my apple juice made me choke.'
Alex: So then how come it is not in the dictionary?
Justin: Well now it is.
