👉 The term "quivered" is a slang term used to describe someone who has not been able to communicate effectively or understand someone's words. This can sometimes be due to misunderstandings, misinterpretation of language, or simply poor communication skills. Quivering often refers to a rapid, involuntary twitching of the lips that occurs during conversations when one person is trying to convey something clearly but another person is not fully understanding what was said.
