adj. When a person has consumed so much alcohol that they are beyond the point where they can be described as smashed, crunked or any other common slang. Being tredrunk can result in memory loss, however everybody will have stories about you the next day if you manage to find your way home. Other side effects include vomiting, hallucination, embarrasment (depending on the person), and good night sleeps in random places.
Wow, that bitch is tredrunk!
