San Francisco 49ers quarterback Colin Kaepernick set records in his team’s 45-31 win over the Green Bay Packers in the playoffs on Saturday, and he also inspired a social media trend.

The second-year player has been celebrating his touchdowns with a kiss on his biceps (seen above). After his outstanding performance Saturday — he rushed for 181 yards (a quarterback record), two touchdowns, and threw for 263 yards and two touchdowns — many Niners fans began following his lead by imitating the celebration.

Much like “Tebowing” and “Griffining,” “Kaepernicking” has become a social media trend.
