LeBust
Nickname for LeBron James after he left Cleveland to play for Miami and loosely used words like "championship" and "dynasty" as if they had already happened. They had, just not for LeBron as he helped drag his team down in the 2011 finals loosing to the Dallas Mavericks.
Who would have thought Miami's run for the 2011 NBA finals would be a "LeBust." Also can be used for an individual who lacks respect within their field of expertise, whether that be at work or elsewhere.
