What is the antonym for euphemism? [duplicate]

Euphemism would mean putting across something that is possibly very hurtful in a very polite /mild manner. Is there any specific word for its antonym? The closest to this that I can think of is venomous

The opposite of a euphemism is a dysphemism or cacophemism.

Dysphemism is a figure of speech which is defined as the use of disparaging or offensive expressions instead of inoffensive ones... of negative expressions instead of positive ones. A speaker uses them to humiliate or degrade the disapproved person or character. Dysphemism examples may be classified according to the following types.

• Dysphemistic Epithets: animal names are used, like “pig, bitch, rat, dog or snake”.
• Homosexual Dysphemism: these terms are used regarding homosexuality like, “gay, faggot and queer”.
• Synecdoche: it is used to describe something as a whole like, “she is a prick.”

"You do not varnish the truth."

This was said by the outlaw Ned Pepper (played by Barry Pepper!) to the 14-year old protagonist who spoke her mind to him.
