A giant, raging boner, capable of slaying the leader of the worldwide Catholic church.

Jeff the killer 

Jeff the killer is a creepypasta that has bunches of fangirls/fanboys *wink-wink nudge-nudge* that think if they ever meet Jeff he will spare them from their death for whatever reason and spontaneously fall in love with them and become their boyfriend because the world is fucking crazy enough as is and it's all ready a giant wattpad story why not add that too

But I think Jeff the killer has a super cool story and he seems like a super radical dude dX

All Killer, No Filler 

A way of saying that every piece of something is excellent and contributes to the thing as a whole. That nothing is put in to "fill" space.

"Hey man, did you hear that new insert band album? That thing is all killer, no filler."

curve killer 

That one person in class who scores significantly higher on a test than the rest of his peers resulting in the grade boost/curve being rendered useless. Curves often give the highest grade an A but if the person has close to an A there is either a very small curve or no curve at all despite everyone else's grade.

James: Mr. Johnson said that he was gonna curve the grade on that test! I only have a 33. What did you get Morgan?
Morgan: I got a 92
James: Aww! You freakin curve killer.
