shirt nipple

when you pull on a shirt of a certain material, causing a section of it to stick out and stay that way until smoothed out.

Person 1: "It's so hot out my shirt keeps sticking to my stomach" *pinches / pulls bottom of shirt out*
Person 2: "Now you have a shirt nipple"

New shirt nipples

When someone forgets to iron out the creases that intersect at the nipples on a new dress shirt. They are seen most often at weddings and other formal events where people who rarely dress up are forced to.

"Check it out! Terry forgot to iron out his new shirt nipples!"
