The phrase "more forever" can be used to describe something that lasts for an extended period or seems to have no end. There are several synonyms that can be used instead of "more forever" to convey the same meaning. "Indefinitely" is one such word that can be used to indicate a never-ending duration. "Perpetual" and "endless" are also synonyms that describe something that lasts forever. "Eternal" is another word that denotes something that exists forever, without any end. On the other hand, "incessant" and "uninterrupted" can be used to describe something that continues without pause or pause forever.
