There are many ways to insult Puerto Ricans that aren’t related to the way they talk.  I don’t think Puerto Ricans mind if people joke about the way they talk.  Also, I think it’s a good idea to not make fun of other people at all, because people’s feelings get hurt and they don’t like being made fun of.  If you want to, you can do these other things:

-   Tell them that Puerto Ricans aren’t citizens and shouldn’t be allowed to vote

-   Tell them that Puerto Ricans can’t swim because they have poor eyesight

-   Tell them that Puerto Ricans aren’t really Americans

There are several things that can be used to insult them.  One is to call them “dirty Puerto Ricans”.  “Dirty” is a word that’s often used to say that a person is bad.  Another is to call them “dirt-eaters” or “dirt-eater-Puerto Ricans”.  This refers to a specific slur against the people of Puerto Rico, which is that they are supposed to be dirty and eat dirt.  Another is to refer to them as “Doric Island-niggers”.  This is a racist and insulting name for the people of Puerto Rico.

What are some insults for Puerto Ricans?

Many Americans seem to think that it’s funny to poke fun at Puerto Ricans, because they use many Spanish words and have a Spanish accent.  But I don’t think it’s very funny, myself.  I think it’s more correct to use standard English words, and that most people would prefer to be called “Puerto Rican”, rather than using some slang.
