Bed Ninja

Similar to a sexual ninja. Someone that is sneaky in the sack, getting in and out before either party have time to notice. Not normally a good thing...

"Hey, I heard you left the party with that Tom guy last night, giggity giggity?"
"yeah, but I don't think I'll be seeing him again, I barely noticed anything had happened."
"oh, a bed ninja huh? Those are the worst!"

Wank Ninja

Someone who is very skilled at wanking covertly in the same room as another person - the master of risky wanking. The Wank Ninja can successfully wank in a number of locations without being detected: in the back of the car with their family, under the table during a meeting, on the sofa next to a friend, etc. The art of the silent finish is vital, as is suppressing any hint of the Orgasm Face.

The other night, my girlfriend totally managed to get herself off three times during dinner with my grandparents - she's such a wank ninja.

Ninja Beers

Little cups of wobbly pop that are sold for insanely low prices at bars on select evenings. Ninja beers sneak up behind you very quietly until BYAHHHHHH....they knock you out cold.

Ninja Beers
"How much are the little guys?"
"a dollar"
"a dollar?? give me five...(ten...fifteen...thirty seven)"
"are you sure?"
"dont you tell me what im capable of drinking"
"oook here you go"
"thanks hot bar lady"

........at this point the Ninja Beer Ninjas are surrounding you waiting for you to drop your guard for the split second they need.....

Poo ninja

The stealthy little bastard that haphazardly leaves brown marks on your undies. Also acts as a scapegoat to take the blame for unexplained events for which you would normally be blamed.

Also known as the pantie assassin (for girls :-p )

Damn - the poo ninja's dealt to my tighty whities!

Dad: "Where'd all the change from my jeans' pocket go?"
Son: "poo ninja must have got it."
