Tit-Nippin

When it is so cold and your nips are so hard you HAVE to put on a sweatshirt to cover them and they still stick out....

Damn, last night it was so cold my girl was straight up tit-nippin!

Nippin Out

When a woman's nipples become erect. When a woman's nipples are hard. When a woman's nipples are visibly erect and or hard through her clothing.

She was definitely "Nippin Out" as Her nipples were obviously seen through her shirt.
