The dance move you may have seen on social media and dance floors has now made its debut in the US Congress .
Cal, the teenage son of Roger Marshall, who on Tuesday was sworn into Congress as a Republican representative, decided to dab in the background his father's big moment.
US House of Representatives speaker Paul Ryan was in the middle of 300 ceremonial swearings-in of new Congressmen when the 17-year-old seized his opportunity.
Mr Ryan was so surprised by the dance move, he turned to ask Cal if he was okay. He tweeted later that day that he still didn't "get what dabbing is".
Mr Marshall tweeted on Tuesday (local time) that his son had been grounded.
