Neologism - Rangent

Have you ever gotten side tracked while talking, telling, or teaching and find yourself in the middle of a tangent that really sounds more like and angry rant? If you have, then have I got a word for you...Rangent. A rangent is a tangent that is a rant. It combines the best of both world without having to limit oneself to one or the other. A rangent is an off-track statement only very loosely connected to what has been talked about and continues on in such a fashion as it becomes both angry and agonizing.
