An "M DOT" is a nick name for a crazy, tough, risk taking person. It's a way to describe someone in a fierce and violent way.

A m dot is the conscious placement of DNA'd aura on the DNA of another person's body, to protect, direct and inform, it must be age appropriate and consensual on the part of all parties involved.
Is that a m dot or a parasite?
