Mary Poppins

1. Perfection.

2. Those stupid girls who look good in a fucking sack and can play in mud and look like a beauty queen. They get the promotions, the pay rises and the gorgeous clothes.
You secretly want to stab these people in the back on the head with scissors.

1. Aaaah! Look at that skirt! You would look Mary Poppins in it!

2. Oh fuck me! Leah is such a Mary Poppins I want to stab her in the back of the head with scissors

Mary Sue

An OC (Original Character) that is basically the best in every way possible. Usually they have a disproportionately large chest, rainbow hair and a dark backstory. They usually have names like, 'Princess Rainbow Sparkle Killer Kawaii Desu' or, 'Miss Sexy Thang Sparkle Rainbow Queen Psycho Killer Shiny Beauty Girl'.

That biatch is nothing but a careless, insincere Mary Sue!

~or~
My eyes are bleeding, and critique would do an indescribably large number on this, I think it's a Mary Sue!

Mary Mcdonnell Syndrome

or M.M.S.
A severe mental syndrome characterized by excessive grinding of the teeth and chewing of the jaw. Named after the famous actress Mary McDonnell who developed this rare and unheard of syndrome during the shooting of the film "Donnie Darko" (her chewing is seen in the family dinner scene) Patients are usually extremely angry and unstoppable when having MMS.
There is no cure for MMS and comes and goes in various frantic episodes. Patients must usually be strapped down to prevent assault on others.

A typical episode characterizes the slight jaw movement on a patient. The patient loses his patience and begins eating extremely fast and angrily. MMS patients get extremely thirsty due to excessive chewing of the gums, so they typically angrily and quickly drink large amounts of water in short periods of time. The patient then gets impatient with everyone around him, usually succumbing to fits of rage and chewing on other people. The MMS patient is fully aware of the oncoming and happenings of MMS, but they simply cannot control it. They typically leave or go for a run due to embarrassment. All of these characteristics of Mary McDonnell Syndrome. The whereabouts of Mary are still unknown today.

Mary Lou Retton 

In celebration of both perfect technique and perfect dismount, the term used to describe a bowel movement that required no wiping and left no evidence in the toilet.

I couldn't believe that I had to drop a deuce at that party! Thank goodness Mary Lou Retton showed up, and left not a trace of evidence.
