Lucky Cinder-Block 

A) The Lucky Cinder-Block is a fictitious object carried by backpackers and students. It represents any extremely heavy object carried for no particular reason.
B) Any useless, weighty, or otherwise pointless object occupying an inordinate amount of space in a backpack.

Steve: Hey Joe, Why is your backpack so heavy?
Joe: I don't know.
Steve: Dude, you brought your lucky cinder-block along didn't you?

Lucy Black 

Lucy Black is an amazing example of Internet fuck puppetry. She is the epitome of style, class and sex on legs. She carries herself with grace and poise, while tearing the heart from men in a single dox. To cross Lucy Black is to sign your own rage certificate.

"Guys, Lucy Black is on this RIP page, stay out of her Medusa stare!"

Internet- "FUCK! RUN FOR THE HILLS"

Black hole of bad luck 

When you're so unlucky that it rubs off into another person who may, or may not be as unlucky. For this person it is very hard to have any type of good luck, but watch out! You may just find someone who is willing to share a half! See "half moon cookie"

Now we are stuck in this place until who knows when. Man, you are such a black hole of bad luck!
