What does it mean if someone is squeaky?

If someone is described as squeaky, it can mean several things depending on context. Literally, it means their voice is high-pitched, small, or makes squeaking sounds, like a child or someone with a high voice, as in she has a squeaky voice. Figuratively, squeaky clean is a common phrase meaning morally very clean, innocent, wholesome, and without any bad record, often used for someone with perfect reputation, as in he has a squeaky clean record. A squeaky person could also mean someone who complains a lot in a high-pitched or annoying way, similar to the saying the squeaky wheel gets the grease, meaning the person who complains loudest gets attention. In some slang, squeaky means someone who is nervous, timid, or easily startled, making small squeaks. In other contexts, squeaky can mean overly proper or prim. If someone is called a squeaky toy, it is usually teasing about high laugh. So being squeaky is not necessarily negative, it can mean innocent and clean as in squeaky clean image, or it can mean high-voiced or complaining, depending on tone. Context determines whether it is affectionate, descriptive, or mildly insulting.
