The forced expulsion of the contents of one's stomach onto oneself, usually after imbibing huge quantities of alcohol, followed by abrupt and unannounced contact with random individuals in the vicinity.
Did you hear what Guy did up at his place in Boston this past weekend? He drank one too many pina coladas and proceeded to vomikaze everyone else there. GROSS.
Vomiking is the act of vomiting out of your nose instead of your mouth. While this is not a true medical distinction, it is funny and should be.
A woman came into the emergency room because she was sick. When the doctor asked the reason for her visit, she replied that she had been "vomiking". The doctor corrected her and said that she had been vomiting, but she replied No, she had been "vomiking". He paused for a moment, not sure what to say next, because the woman was obviously sure this meant something else. He decided to ask her to explain the distinction, to which she replied "vomiting is when the food comes back out your mouth, vomiking is when it comes back out your nose."
