Ninja Nipples

What a woman has if she goes all day without a bra on and no one noticed.

We were out all day with Jane and never noticed she wasn't wearing a bra. It was nipply out and she wasn't wearing a jacket either. The woman's got ninja nipples!

ninja fart

A silent, yet super stinky fart.

I love to release my Ninja Farts just before exiting the elevator.

panty ninja

A guy who is able to stealthily infiltrate, using charm or bravado, almost any female's defense barrier, namely whatever pantywear is "defending" her lower territories.

Greg: Yo, Eric, can you believe TJ hit that blonde chick's gash last night?
Eric: Shit, man, TJ's a freakin' panty ninja.

Although Meegan was really a cum dumpster, she often acted demure so guys would feel like panty ninjas when she finally pulled down her drawers.
