Ninjas on the lawn 

Along with paranoia, ninjas-on-the-lawn is the most common side effect of cocaine.

asshole: "What is that outside?"

you: "I'm not sure, but i think it could be NINJAS."

asshole: "There are no ninjas on the lawn."

you: "OF COURSE THAT'S WHAT THEY WANT YOU TO THINK; THEY'RE NINJAS."

ninjas on fire

A synonym for something so kickass it could only be Halo 2. Stems from a speech by Jason Jones.

"Halo 2 is alot like Halo 1, except it's Halo 1 on fire going 120 miles per hour through a hospital zone chased by helicopters and ninjas. And the ninjas are all on fire too."
-Jason Jones

ninjas...hundreds of them 

A common statement on LUE a board of gamefaqs, where there is an "erotic" story and at the "good" parts you see "NINJAS...HUNDREDS OF THEM!"

One day I was having sex with my girlfriend and then out of the blue, NINJAS...HUNDREDS OF THEM appeared on my couch!
