page 511

Something that NEVER happened. Never ever mention this. It was a mistake. Run now, and never mention this again.

"Hey remember page 511?"
"Shut up or I will murder you and mail your body parts to your family."

Page 511

Don't. Just don't The cursed number itself does not exist to TSC fans, Malec shippers especially.

Friend: What did you think about page 511?
Me: *whirls around* We DO NOT speak of that. Understand me? *Goes and cries in corner*

page 511

A terrifying page from City of lost souls (Cassandra Clare's Series The mortal instruments) It's often ripped out of the book and burned or otherwise destroyed. Most fans deny its existence.

Don't even mention it, it's awfulness in person

"Omg last night I cried when I read page 511"
"What page? There isn't a page 511 in city of lost souls, what do you mean?"

5115

Commonly used as a substitute to SUS on places where you can only put numbers.
Since you only need to replace 5 with S and 11 with U

"What's your age?"
"5115"
"What?"

511

Someone who knows everything. They interrupt you and finish your sentences with something they've done better.

That bitch is a 511 cause she knows more then 411.

Have a question? Go ask Penny. She's the 511 cause she knows more then Information.

511

511 is a step beyond 411.

411 is information.

511 is TOO MUCH information. (substitute for TMI)

Dude- telling me about your digestive issues is just 511 .
