A nice guy, one of the nicest you’ve met. The type of guy who makes you want to try to be a better version of yourself without making you feel less in comparison.
MD/md is an abbreviated form of My Dilemma. It is generally used to express the lack of a clear decision/choice when faced with multiple paths.
Girl : Do you want to get married?
Guy : I don't know if I want to get married and need a girl for that or I want to fall in loveand then marry as a result. It's just md (my dilemma)
