As Rep. Roger Marshall (R-Kansas) was getting sworn into The House of Representatives on Tuesday, something very unusual happened during a photo op.

In one of the photos, House Speaker Paul Ryan holds the Bible as he stood next to his teen son, Cal, oblivious to what he was about to do next: dab.

“Dab” is a dance that was first evolved in Atlanta by hip-hop artists. It is when one drops the head while raising an arm and elbow as if covering the face to sneeze.

When Ryan caught site of the audacious act, flummoxed as ever, he asked Marshall's son, “You alright? You want to put your hand down?”

Ryan then tried to put Cal’s arms down. After all, they were right in the middle of taking a picture.

“Ok, ok, I’m sorry,” the teen laughed.

“Were you going to sneeze, is that it?” Ryan asked.

“He’s sneezing,” the new congressman said.

Some people on social media found the whole entire act, well, silly.

 “What is wrong with my generation? Why are we incapable of doing simple things without being edgy or stupid? It's concerning,” said a Twitter user.

Not too long after the video of the swearing ceremony went viral, Ryan later tweeted: “Countless cute kids. Still don’t get what dabbing is, though.”

“If you don't know what dabbing is...we'd be more than happy to educate you. #LegalizeIt,” wrote one Twitter user.

Furthermore, Marshall later tweeted early Tuesday afternoon that the speaker has grounded his son.

According to BET, no one knows for sure who is the main creator of the "dab," but one thing is for sure: hip-hop artist and Migos member Quavo said the "dab" has been around “for about two years.”

It immediately became popular with the help of artists Skippa Da Flippa, Migos, PeeWee Longway and Jose Guapo, as well as many athletes such as NFL player Cam Newton, a quarterback for the Carolina Panthers.
