Nippin' Titties

When you're horny and you're nipples get hard. Similar to getting a boner.

Alex is always so god damn horny he's always nippin' titties. Maybe it'a because he lacks a penis.

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!
