1. n- the inability to perform when it matters most. A reference to the choking of LeBron James in the 2011 NBA finals to the Dallas Mavericks and Roberto Luongo letting in a total of sixteen goals to the Boston Bruins when leading the series in the 2011 Stanley Cup Finals.

2. n- someone or something completly overrated in every possible way shape and form. Just like Lebron James and Roberto Luongo.
