give (someone) the chair
1. To execute someone by electrocution by means of an electric chair. Primarily heard in US, South Africa. Some states will still give a prisoner the chair if they so choose.
2. In professional wrestling, to hit one's opponent with a metal folding chair, which is used as a prop during the performance. Primarily heard in US, South Africa. I was shocked to find my kindly old grandmother screaming, "Give him the chair!" during a pro wrestling match on TV.
