(pronounced REE) an exclamation expressing extreme joy, fear, sadness, or anger. Used in stressful or overwhelming situations.
You lose your friend on a dark desolate beach and you must find him. You tilt your head back and scream REAGH! REAGH! REAGH! If you do it right, he will "reagh" back and you will be reunited.
