Purposeful Nippling 

Purposeful nippling is going after the nipples with a purpose like are you gonna bite them? You want to lick them? Or can I just get a nibble. Simply put, it’s going at the nipples with a purpose. As opposed to accidental nippling where somebody’s nipples end up in your face and you’re overwhelmed by the nipple and compelled to put it in your mouth and do something with it. See accidental nippling for this.

My pepperoni nipples inspired some purposeful nippling last night.

Nippleroni

Nipples (specifically the aureola, or dark part surrounding the nipple) that are as wide as a pepperoni slice. A portmanteau of "nipple" and "pepperoni".

Damn! She got some nippleroni thumbples I want to suck on!

Nipplizing

Nipplizing:
1:a) Harassing and/or taunting another human being using only the nipples.

b) Nipple-jabbing. Pretending your nipples are weapons and attacking another human.

Nipplizing is a hate crime and should never be tolerated.

Nippling 

"To touch, pinch, or grasp the mammary papilla in an aggressive non-sexual or sexual manner."

"I'm going to give you a hard nippling tonight, babe."
"If you don't shut up I'm going to give you a nippling!"
*Nuzzles your cheek and gives you a nippling* "UwU."

Nippling 

Atmosphere that is cold enough to perk your nipples.

It's kind of nippling out here, isn't it?
