Attacked by Ninjas 

When you are on your back and watching your phone and you lose your grip so the phone bonks you on the head.

I was lying in bed the other night when I was attacked by ninjas.

Monkey-Cheese-Ninjas-Pirates 

Nerds who think they're "random" and hilarious because they yell out shit like "Monkey! Cheese!" and laugh their asses off.

If I hear one more thing about waffles from that Monkey-Cheese-Ninja-Pirate, I'm leaving.

She is really annoying in a monkey-cheese-ninjas-pirates way.

army of ninjas

Irrational fear or paranoia.

"I don't know why you have a password on your screen saver, Bob. It's not like there's an army of ninjas waiting in the air ducts to steal your porn."

there's ninjas on the lawn 

Its a less racial way of saying there are black people somewhere on your property. We say it when blacks show up at our haunted house. The blacks are usualy the ones that hit our monsters and get all kung foo on that ass when they get scared. So when they show up, a call goes out over the radio that "there's ninjas on the lawn"
I have also used it when there are black ppl around my store. Like when they hang out in the parking lot doing nothing.

I saw a group of black people headed for the entrance to our haunted house, so I alerted the managers that there's ninjas on the lawn.

Some "panda bear ninjas" came down the street and stole my wallet and my girlfriend after beating the shit out of me.

surf ninjas 

One of the coolest movies ever made. About 3 brothers who live on the beach in California but find out that they are princes for some foreign island in Indonesia. The comic relief has a magical power where if he says "what if this happened" or "that would suck if this happened" then it would happen, plus, he's an idiot. Also, it's rated PG. Rent it TODAY!

Nate - hey, Bryan, have you watched the cooly awesome movie Surf Ninjas?
Bryan - Oh, uhhh... no.
Nate - *shoots Bryan in the face*

the ninjas again 

As in " I think its those ninjas"; finely honed deduction; a proclamation of the usual suspects.

"I think its those ninjas"
"Well, i agree it must be the ninjas again."
