A twitter trend started by @odetobenedict, @Colbster221B and @sasstrade. Swaggy and non-explicit version of nipple. Used if you are too ashamed to use nipple in a formal conversation
(In a social gathering)
Boy: Show me your nopples.
Girl: (whispers) You're not swaggyenough to use that word yeah byeeee.
Boy: YIPPEE KI-AY MOTHER FUCKKAAAAAAA!
Nipples (specifically the aureola, or dark part surrounding the nipple) that are as wide as a pepperoni slice. A portmanteau of "nipple" and "pepperoni".
