Is there another name for pig nipples?

While there's no common slang or alternate term for pig nipples specifically, you could use general terms like:

* Teats: This is the most common and neutral term for the mammary glands of mammals, including pigs.

* Mammary glands: This is a more scientific and formal term.

* Udder: While udder is usually associated with cows, it can be used in a broader sense to refer to the whole mammary system, including the teats, of a female mammal.

It's important to note that using terms like "pig nipples" is generally not considered appropriate in polite conversation.
