It means "to love ones self". The word "mim" means "me" in Portugees. Therefore, it's exact definition would be an individual who loves themselves and can find no one else that appeals to them or their standards thus staying away from the realtionship scene. Some would say these individuals are vain and full of themselves but to any Mim-sexual this is one of many ways of eaither saying their staying away from the pain of a relationship or they're just not interested in sharing their love with others.
I do not think anyone else is worthy of the love I have to give I love myself and don't think anyone elses deserves me but me therefore I am a Mim-sexual.
