Mary Call 

Mary Calls are knows to be amazing once you first meet them, but as you really get to know them, you'll see how shitty they are and how manipulative they can be. They will do anything and everything to make sure you do what they want. You don’t realize how you’re being toyed with until you have a falling out, you will definitely have many of those. And every single time they promise to be nice about it and say they’ll never hurt you again, it's a lie. They say they’ll get better. Bullshit. More lies.

In short, Mary Calls are not to be trusted, when you see them, Avoid! Avoid! Avoid!
Save yourself.

"Yo Johnny! Look at that Mary Call over there! She's such an asshole!"

Mary Call 

When a colleague from work phones you hammered all the time, usually from copious amounts of wine or beer, and there’s no escape!

Jesus Christ man last night I got a Mary Call went on for hours, talking utter shite, friend: yeah me too. The Mary tends to have no recollection of having done this and will no doubt do it again.

To do something that is not exactly the most effective course of action in the face of an emergency or disaster. See "death of Heath Ledger".

George W. Bush, when he learned about the attacks on New York, pulled a 'call Mary-Kate' when he kept reading that children's book to those kids.
