A group chat on Instagram which is made up of fans for the musical “Be More Chill”. MMBF stands for the group chat’s name, “michael mell’s blood fetish!!”, named by the creator of the chat. Of course, the members of the group chat don’t want to say the full name, so they just call it MMBF. MMBF also has its own Instagram account. The members of the chat are trying to make MMBF the most iconic group chat in the “Be More Chill” fandom. They’re pretty confident in their abilities.
