Literary authors employ the term "slacker" in diverse ways that reflect both character judgment and descriptions of physical or metaphorical decline. In some instances, it appears as a disparaging label for those considered lazy or irresponsible, conveying a nuanced moral failing or failure to meet societal standards—as when a character is deemed lazy and unworthy of admiration ([1], [2], [3]). At the same time, writers use "slacker" to evoke the image of something losing strength or firmness, whether in the gradual slackening of a grip, the deceleration of a tide or machinery, or even the waning fervor of a battle ([4], [5], [6]). This dual usage—merging social criticism with vivid physical description—demonstrates the word's flexibility as both a pejorative for human behavior and a dynamic descriptor of diminishing intensity ([7], [8]).
