A bumpy nipple. Usually with a few sprigs of nipple pubes on it. Gross enough to turn you off completely. The bumps can be seen through light t shirts and most bras.
Guh, did you see her numples? I wanted to puke!
Dude, that chick had a set of numples that spelled “gross” in braille! I was really into it!
I don’t believe a numple should shove through a padded bra AND a sweatshirt!
