A mimf is a definition of a person who is mentally ill, for using it as a joke with friends. The exact meaning to MIMF is:
M - Mentally
I - Ill
M - Mother (you can also use monster, it's what fits best with the person you're describing.)
F - Fucker
For example:

Lila: "How are you doing, John?"

John: "I'm feeling like shit, but don't worry, I've been a mimf for a long time now."
