M.D. 

MD stands for Master's degree in Doctor wannabe.
The people that are good candidates for this credential behind their names, are people that think they know everything, snobby, pathetic in life and couldn't do much because they ended up being an MD for someone else. Most likely their parents wishes and not their own.

Son: "I think I'll go get my master's degree in doctor wannabe. So I'll be an M.D., and pretend to save lives like in T.v."

Dad: "Good choice son, I am proud of you."
Son: "Oh, Father!"
*hugs*

See. Doing it just for the parents, especially if the mother is a CCRN and developed a complex because she couldn't be a real doctor because she was a hippy.

1. Medical doctor.
2. Major depression.
3. My dick.
4. Muff diver.

I went to see the M.D. I think I am suffering from MD, because this girl I dig wants nothing to do with MD. Guess she's a MD!

M&D

M&D is a shortened version of “Maddie and Damien.” Two adorable characters in a story being created by an adorable person. They’re like Bonnie and Clyde and stick by each other’s sides no matter the amount of danger they’re in.

“Well if it isn’t M&D...” Said William, before stepping into Maddie’s trap.

M-d 

A title for a forum Moderator that originated in MySpace Religion and Philosophy forum. Much like Jews often write "God" as "G-d" out of respect and reverence, many R&P regs have been known to do the same for their M-derators.

Blessed be M-d, King of the R&Pverse, who deleteth spam from the interwebz. May His mighty banhammer fall swiftly upon the heads of trolls.
