* Overused: The phrase is widely known and used, indicating it's been around for a while and is likely to be familiar to most people.
* Lack of originality: Its meaning is clear and direct, implying close friendship or a strong bond. It lacks a unique or creative twist that makes it stand out.
* Predictability: Because it's so common, readers or listeners may anticipate the phrase when they hear the first part ("thick").
However, clichés can still be effective in writing or conversation:
* They create a sense of familiarity and understanding: They provide a shortcut to communicate meaning quickly and efficiently.
* They can be humorous: Using a cliché in a humorous or ironic way can make it more interesting.
* They can be memorable: Some clichés are so ingrained in language that they stick in the listener's mind.
To determine if it's appropriate for your specific context, consider the following:
* Your audience: Is it a group that might find the cliché tired or predictable?
* Your purpose: Are you aiming for originality or using it for humor or emphasis?
* The overall tone: Does the phrase fit the style and tone of your writing or conversation?
Ultimately, while "thick as a thief" is a cliché, its effectiveness depends on how you use it.
