Nippin

When your nipple outline protrudes from your outermost layer of clothing

Last night when John had to walk home in the cold, I noticed him nippin due to the lack of winter clothing.

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!
