Capital Ex 

That one ex you always think of first when someone says "your Ex". No matter how many ex-girlfriends or boyfriends you have, there is always going to be one who stands out in your memory, one who you always think about unbidden. Normally this is the ex who had the most serious relationship with you. The phrase "capital Ex" is used to differentiate.

The "E" is capitalized.

Rob: "Hey man, I ran into your ex today. Turns out she's lesbian now."
Jon: "Shelly?"
Rob: "No man, Jenny. Why do you always think I mean Shelly?"
Jon: "I don't know. I guess she's just my capital Ex."

No matter how many exes you have, there's always that one Ex.

Reyus Ex Machina 

A character in media who knows how to do everything without training or explanation like Rey from the new Star Wars Trilogy.

This character breaks the entire Star wars mythos surrounding the Jedi. She has never once been shown to train or be trained in the force but can do feats it took Jedi masters years to master. She's surpassed Mary Sue. I hereby dub her a Reyus Ex Machina.
