MM2 Pros 

It's simple; pros in Murder Mystery 2 (MM2) on Roblox. They range from 11-21 in age. MM2 pros commonly wear the stitch face and use the zombie animation, and the girls have boxy legs. They more than likely have the elite game pass and 10+ godlies, in which they don't use more than half of them; they're just there to make them look good on their nametag with the I, II, III, IIII, X, and IX. Oh, and they also blast LOUD trash ass rap on their radios.
I hate MM2 pros. They're toxic and annoying.
