Dysphemism is the use of a harsh or more offensive word instead of a more polite or agreeable one. It's the opposite of a euphemism and is often used to shock or emphasize negativity.

In storytelling or speech, dysphemisms can be used to create a stark impression or to convey strong emotions. 

Referring to a ‘shack' instead of ‘humble home' can color your audience's perception.

A character might say, ‘He's not thrifty; he's a cheapskate,' to emphasize disdain or judgment.

Someone—not you of course—who wanted to use a dysphemism, might call this video series “words FOR the weak” instead of “words OF the week.” 

Dysphemism can express strong disapproval or paint a picture of severity and urgency.
