Sneaking Suspicion is a term that can be used to describe a feeling of suspicion or distrust that someone has without being able to explain why. It is often associated with a HUNCH, an IDEA, or a THEORY. A HUNCH is a feeling or intuition about something, an IDEA is a thought or opinion about something, and a THEORY is a set of ideas or principles that explain or guide how something works. All three terms can be used to describe Sneaking Suspicion.
