The boys of Stray Kids showed fans that they can roast one another like there's no tomorrow, for 'Besties on Besties' with 'Seventeen'!

For this fun, casual interview, the Stray Kids members took on the 'Besties on Besties' challenge to demonstrate their close-knit bond. First, the challenge started off with questions focussed around the group, like, "Describe your friendship in three words", "Who texts the most?", etc. Then, the challenge moved on to questions focussed around the individual members, one by one. 

The individual questions definitely allowed Stray Kids to bring out their savage jokes full out, especially Seungmin! For question question #4, which asked to fill in the blank after "Bang Chan is so...", Seungmin raised his hand and said out loud, "Bang chan is so old!"

As Seungmin continued to make his members laugh with his vicious answers, the other members all joined in, filling the studio with laughter and applause. Watch the full clip of Stray Kids taking the 'Besties on Besties' challenge, above!
