Stray Kids' Changbin is known in the community for being very buff. And BM or Big Matthew's Big Tiddie Gang which is also known as the Big Tiddie Committee, is a group of men with large pecs. Some of the most well known official members are Wonho (Former Monsta X member) and Hongseok (Member of Pentagon). Over the past year Seo Changbin has devolped enough "tiddie" to be excepted into this exclusive club.  This is an important matter because we want to be able to keep this gang up to date and it would be rude not to acknowledge him as a legitimate canidate.
