Male name- comes from taking the initials of either
two first names, a first and middle name, or sometimes even a
first and last name.
JD's are typically really good looking, very smart, funny, respectful, and easy to get along with. Most often they are also somewhat shy. If you are a girl, you will most likely find yourself very much attracted to a JD even if he is completely oblivious to it.
If for some reason a JD isn't too shy to talk to you (eventually) then you are very lucky.
