Ninja Turtle Feet

The way socked feet look after spending time in flip flops.

Didn't have time to put on shoes this morning, guess I'll have Ninja Turtle Feet for the rest of the day.

flying ninja monkeys

Flying Ninja Monkeys(AKA FNM's) were once the dominant race on this planet...however after hundreds of years of war between them and Flying Ninja Gorillas(AKA FNG's-see Flying Ninja Gorrilas for definition) the FNM's decided to hide their survivors and reamin in secrecy...only recently has their been rhumours of 2 wise men known as Corby And Vahon, have been able to command these FNM's...i was among the first to fall to their extreme power...WARNING: let no force ever underestimate their power.

Bushes presence in Iraq is not only for the oil....that is a cover story....he is looking for the power to control FNM's and FNG's

ninja rock

a ninja rock is a rock that sneaks up on you while walking or running and causes you to either twist, sprain, or break your ankle. At the very least it will make you say ouch that hurt. Most commonly happens at night when you cant really see whats on the ground so well.

I was walking to the chow hall with my roomies and out of nowhere this ninja rock made me twist my ankle.

Aww fuck damn ninja rock just tried to take me out. I hate those sneaky bastards.

Dude Caleb was walking to back from the store last night and stepped on a ninja rock. It put him on crutches man.

Ninja Penguin Buddy

(AKA NPB) When someone sneaks over to your house at 3 in the morning to put a penguin, of any sort, on your balcony using ninja skills. This is usually done to show someone that good things do happen to good people. If the penguin is accepted by the receiving person then the two become Ninja Penguin Buddies.

Dude, have you met my Ninja Penguin Buddy yet? He is totally legit.

Ninja Heart Attack

In any video game:
When death occurs for an unknown reason.
Nobody knows how it happened.
Nobody knows why it happened.
Nobody knows WTF happened.

But, it's fucking hilarious.

Guy 1: "WTF, did Jesus just snipe me?"
Guy 2: "Bro, I have no clue you just fainted."
Guy 1: "Fucking Ninja Heart Attack, damn it."
