Warui Kotoba - Swear Words in Japanese
In Japan it is not customary to speak slang of sexual connotation in public, nor profanity of this type, there are some cases and diversities, but the profanity we know here are not used in Japan in a common way.
People often translate these swear words and insults in Japanese incorrectly, making it seem that a certain word is equivalent to something immoral or offensive in Portuguese. Rarely will a Japanese word be like that, but it can have the same impact.
We noticed, that they translate things that have nothing to do with Fuck or Fuck. I watching an episode of No Game No Life and the protagonist says: dameda [ダメだ] which means Useless, and the fansub subtitled it as fucked up.
It is worth mentioning that, yes, there are taboo words with sexual connotations, offensive and terrible, but they are not commonly used to insult others. Warui Kotoba [悪い言葉] is a common term for bad words, but it is not the only term, or the most used.
I made a video explaining more about Japanese swear words and their pronunciations and meanings:
Bubetsu - Insult - Scornful Words
There is a Japanese word called "bubetsu" [侮蔑] that can be literally translated as contempt or insult. Unlike "warui kotoba," the word bubetsu is not limited to just words or actions, but also to depreciative feelings and their intent.
In fact, bubetsu is a standard term for the many synonyms and phenomenological forms of contempt that we will list below. In addition to swearing, you will learn the different categories of insult in Japanese:

In Japanese, many synonyms were generated when ideograms were imported and evolved over time, this gave rise to dozens of types of contempt and insults shown above and also to many synonyms and variations of swear words.
In the past, there were Japanese poems and decapitations in the Nara and Heian eras that applied the rhetorical technique of Kanji to insult. Things are not limited to words alone, some people often create hidden puns or use sarcastic spelling errors.
Higo - Vulgar and Pejorative Swearing
When it comes to swear words or bad words, the term Higo [卑語] can be used to categorize abusive words that should be avoided in public. Some words are commonly used in insults, while others are quite underground.
Words in this category most often refer to slang for genitals, intercourse, excrement, semen, buttocks, breasts, and other related words. You may be interested in reading the article on sexual words. See some:

Understanding Japanese swear words
We can see that Japanese insults when translating do not have a correct meaning, they can mean several words in English, we also notice the use of additions and modifications of words, as in the case of different forms of insult that use the word ばか (baka).
だよ - Dayo - Few examples were mentioned here, but many insults end with the word Dayo, to confirm, emphasize and increase the insult. Dayo is one of the forms of the verb "to be."
It is also common to mix other insults to enhance them, such as in the case of Baka + Aho / Baka + Yaro / Baka + Mono. It is possible to use them even as a prefix or suffix in names.
It is also worth ing that profanity and some insults can be written in Katakana, as in the case of バカ, in addition to being often seen in katakana in manga and books, to cause a strong and special effect.
There are also insults using the term "Você" itself, such as in the case of "kisama, temee," which means you, but depending on the tone of voice or the region, it can be an insult.
We also have another article that talks about the swear words in Japanese anime. In this article, you will learn in detail about the main words heard in anime such as: "kuso, uzai, chikushou, baka, aho, yatsu, shinee, debu, nanda, temee".

The Japanese also like to belittle another person using words of honor. By implication, we can use good and magnificent words to give honor exaggeratedly and sarcastically.
Others use their own spelling or mispronouncement on purpose to mix up or create some sarcastic insult. In fact, there are thousands of ways to insult people in Japanese. Over time we will update you!
