when a shirt is so tight that we can see the persons nipples. It is very visible and can be seen about 30 feet away from the person wearing this.

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"
Person 2: "Now you have a shirt nipple"

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.
