San Francisco 49ers quarterback Colin Kaepernick's last name became a verb after his iconic muscle-flexing bicep-kissing move while celebrating a touchdown in the end zone. The "Kaepernicking" craze began after San Francisco's 45-31 victory over the Green Bay Packers in the NFC divisional playoff. Kaepernick has filed to trademark the move.
