A member of a not-so-secret and vaguely homoerotic society originating in Danville, California. A Nipple Ninja is fluent in many techniques of nipple flipping, and performs his art on unsuspecting victims. These moves (examples include: The horseshoe, the rainbow, the monkey wrench, and the Horny Hungarian) can be performed in friendly or unfriendly situations.
When you're about to cum, twist the girl's nipples as hard as you can so she freaks out and screams and is distracted, oblivious to the fact that you're blowing inside her

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!
Someone who jumps from one relationship immediately into another one.
Serial monogamists can not stand to be alone and often suffer from vast commitment and insecurity issues.
Because they jump into relationships immediately after the previous one has ended, serial monogamists typically don't take the time to reflect on their behavior or why their previous relationships failed; thus, they end up making the same relationship mistakes over and over again.
