When something is not working properly, we often say it "goes buggy." However, there are many synonyms to describe this situation. For example, we can say that something is malfunctioning, acting up, glitching, crashing, or freezing. We might also describe the problem as being buggy, buggy behavior, or buggy software. Furthermore, we can use phrases like "on the fritz," "going haywire," or "having a meltdown" to add a little more flavor to our description. At the end of the day, there are many ways to describe when something is not working as it should, and choosing the right synonyms can help to communicate the issue more clearly.
