A massive nipple that covers the entire breast can also be mistaken for large hoover accidents. (when somebody is accidently sucked on by a hoover and has a large red circle mark left behind)
Nipplecision is the act of the nip nips being chopped off. Traditionally practiced in Jewish cultures where young boys will get their nipples cut off, similarly to circumcision where the foreskin is cut off. It is preformed by a Nipplecisionist.
