Nipple Tent 

The crease on the front-side of a t-shirt caused by the wearer's erected nipples, in which the nipples are so hard that the fabric is pulled taut, resulting in a noticeable space between the crease and the wearer's body, much like a long tent.

Dude, I am so cold right now.

Yeah I can tell. You're pitching a nipple tent like 3 inches high!

Hey, did you watch pop idol last night?

Yeah! Did you see Simon Cowell's nipple tent?

How could I not?

Being in love with your own nipples, when you admire them all the time; and you can't stop your self from playing with them in public.

Sometimes I catch myself aroused in public and I can't help touching my nipples. I am nipplecentric and I love it.

Tentacle Nipples 

1. A horrific physical condition, probably genetic, in which tentacles extend from one's nipples in correlation with one's bitchy emotions. The tentacle nipples emerge extensively during full moons, sometimes stretching for miles and miles, wriggling grotesquely.

2. A nickname for one who suffers from said condition.

I wouldn't go for him if I were you; he has tentacle nipples.
