How it's used
This idiom vividly depicts a crutch infested with insects, implying that the very tool meant to provide support is structurally compromised and will fail under pressure. It is used to describe people who cannot be trusted to follow through on commitments or objects that are prone to breaking down unexpectedly. The imagery emphasizes a hidden weakness that makes the subject useless when needed most.
Examples
His proposal is like a worm-eaten crutch, completely unreliable.
Ask him for help? He is basically a worm-eaten crutch!
Common phrases
simply unreliable
like a worm-eaten crutch
Common mistake
Do not confuse this with literal descriptions of broken items. It is a metaphorical insult or critique of reliability, so using it for a simple broken object without implying a lack of trust or competence sounds unnatural.
