Jin has played the role of a mother in the group since BTS debuted.
Jin is the "mother" of the group and takes care of his bandmates. For example, he often cooks and cleans for the other group members.  He also advises the others, serving as a good example to them. For this reason, Jin is the best BTS boy. Jin was born on December 4, 1992, and is the oldest member of his group. In BTS, he sometimes does the cooking and cleaning for his members while most of the members do know how to do these. Members and fans feel that he is reliable, so they have a nickname "mom" for him. Jin is the most pretty member of the team and he loves pink, so fans sometimes like calling him the mom of BTS. Jungkook once called him mommy on accident on tv shows. The boys know how vital Jin is for them and how Jin takes care of them. The nickname "mom" is a joke for showing people's love for Jin.
Jin has said in a fan meeting that he doesn't like to be called Pink Princess or Eomma. Eomma means Mother in Korean; they call their biological mother Eomma like we say mum or mother. We should respect his opinion. We don't know BTS personally, they are people we love so we should treat them right. Streaming and voting are nice but lots of ARMYs don't have the basic respect towards them. Furthermore, he is a person with different characteristics to his personality other than simply being labeled as ‘the caregiver’ of BTS. He is so much more than that. By calling him ‘mom,’ you are reducing everything that he is to simply ‘the one that takes care of the group’. Not that that is a bad trait, but it certainly isn’t the only thing that represents Jin.
