creep

An creep is someone who acts sneaky or untrustworthy, often in a way that's unsettling. It can also describe something that's moving slowly and quietly, like a creepy sound.

When we use "creep" to describe a person, it usually means they're being sly or dishonest, but not necessarily malicious. They might be eavesdropping on conversations or snooping around where they don't belong. If someone says you're creeping up behind them, that just means you're sneaking quietly closer.

If we use "creep" to describe something moving, like a sound or an object, it's often in a way that feels eerie or unsettling. For example, if there's a creepy creaking noise coming from the old house at night, it might be because of a loose board or a mouse scurrying around.
