One who is so drunk they cannot stop throwing up for an entire night. They are the entertainment for the other party goers and generally don't remember the night's events. They usually also throw up in a location other than the toilet, such as a bed, a car, on themselves, or on someone else.
'John you were such a yack show last night!'

Annoying whimsical chatter, making no real conversation, similar to that of background noise. To talk idly or incessantly. The southern version of the words is yik-yak.

When in absolute disgust one says "finna yack" meaning, I'm going to puke. Could also express disagreement or physical illness.
