Nipplin' 

When a celebrity on television is not wearing a bra on a particularly chilly set and her nipples are visible through her shirt. Christina Applegate was a pleasant example.

"What're you doing?"

"Watching my new favorite show."

"I didn't know you liked friends.

What are you doing with those binoculars?"

"If you look very closely, you can see that Jennifer Aniston isn't wearing a bra."

"Oh yeah? Nipplin'?" *Takes binoculars?*

nipplin' it 

When a musician, especially a bassist, has their strap adjusted in such a way that their instrument and thus strumming or plucking is at nipple height.

"Man, the bassist plays his bass up high. Really nipplin' it. "

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.
