没用的英语口语怎么说

"Useless" or "useless" is a word that means something is not useful or effective. For example, you might say "This tool is useless for fixing a car" to mean that the tool is not effective or helpful in repairing a car.

However, it's important to note that this phrase may be considered rude or offensive, as it suggests that something or someone is not worth the time or effort. It's generally better to choose more neutral or constructive language when describing something or someone as not effective or helpful.
