It is generally a slang term for someone who has male and female genitalia. Basically someone who is intersex; not all intersex people identify as transgender so no. It's all about what they choose to identify as. I would not suggest calling someone a morfidite even if they are intersex, for they may become offended.
The term "morfidite" does not appear to be widely recognized or used in scholarly or medical contexts. However, the idea of a person who is half man and half woman is often more accurately described by terms such as "intersex," which refers to individuals born with physical sex characteristics that don't fit typical binary notions of male or female bodies. Additionally, "genderqueer" or "non-binary" may describe individuals who do not strictly identify as either male or female. It's essential to approach these concepts with sensitivity and an understanding of the complexities of gender and sexual identity.
