look up any word, like donkey punch:
When something makes you barf so hard that your body searches to the depths of your bowels for something to puke, the result being that you vomit up your own poop (which, when evacuated in this manner, is known as barfeces).
Her 300 dollar pants were so ridiculously ugly that when I saw them I barfecated, covering them in barfeces.
