Under irritation refers to a stimulus or excitation , which is usually of a negative connotation.

Often this is triggered by the discovery of an action or statements by a third party.

In popular parlance was created by the sonic proximity to irr and wrong in the 19th century the importance of distracting, unsettling, disturbing, confusing .
