Ninja Fuck

When you ( a male) is having sex with two other people ( male or female) and you fuck them in the butts back to back. Hence, you see an ASS, you see an ASS, and you went IN, or assassin ( which is a word used to describe a ninja).

Joe Schmoe: Hey bro, I just had a consecutive buttsex with these two smoking hot chicks last night
Douchebag Dan: Duuuuuude! You just had a Ninja Fuck!!!
Joe: Totally gnarly dude!!

Ninja Nap

the act of napping unexpectedly when the feeling of being tired is not present. should be avoided when operating heavy machinery or driving a motor vehicle. preferably takes place on a couch or another piece of furniture; not to be confused with fainting

"i was just sitting there talking to my friend and all of a sudden was hit by a ninja nap"; "sorry, just ninja napped"

Ninja Tuna

A person, so awesome they amaze every person who sees them... they also have horrible B.O. and breath that smells like Tuna, so you are reluctant to approach them but always enjoy there awesomness from afar.

"Carl is so awesome! but he's more of a ninja tuna, so I don't hang out with him."

ninja turtles

The ninja turtles lived in the sewers, therefore they MUST smell like absolute SHIT. So when you pick up a stench that is so bad you can't think of anything worse it must be that the ninja turtles are at your house.

Ashton: "Keisha what the fuck is that smell?"

Keisha: "Fucking Ninja Turtles!"

Ashton: "RIGHT RIGHT"
