1: The Weakest Link is a game show in which contestants answer a wide range of questions while trying to earn more money with each correct answer. The show first started in the UK in 2000, but has been done in many other countries as well.
This show was most popular for its UK host "Anne Robinson", who probably had to be the most annoyingbitch on television at the time. Her shrill voice and expressionless face just left you wanting to reach out and throttle her.
2: Used to describe someone whos intelligence or physical abilities are less then average.
1: "I'd like to slap that Anne Robinson around a bit and show her who the real weakest link is."
2: "Man, we would be winning right now if it wasn't for our damn goalie... hes definitely the weakest link"
