Pushed daisies is a euphemism for someone who has passed away. There are several synonyms or alternative expressions that can be used to convey the same meaning without using the term. Some of these synonyms can include "passed on," "departed," "deceased," "no longer with us," "gone," "resting in peace," "crossed over," and "expired." These words are often used in more formal or sensitive situations to avoid causing discomfort or offense. However, others may choose to use more casual or humorous terms such as "kicked the bucket," "bit the dust," "bought the farm," or "pushing up daisies." Ultimately, the choice of synonym depends on the context and tone of the conversation.
