The phrase “I can’t be arsed” is a British informal expression that means someone cannot be bothered or is too lazy to do something. It conveys a sense of apathy or lack of motivation to engage in a particular task or activity.
For example, if someone says, “I can’t be arsed to go out tonight,” it means they don’t feel like putting in the effort to go out, possibly due to tiredness or simply not being interested. The phrase can be considered somewhat vulgar due to the use of the word “arsed,” which is a variation of the word “arse” (a slang term for buttocks), but it is commonly used in casual conversations.
