SKITCHER

A person who is highly agitated, unstable, unpredictable or generally terrifying in a stop and go type fashion. Meant to be screeched slowly and dramatically in a high-pitched horror movie voice in reference to the appropriate individual (only when appropriate, of course). Can also be used to scare small children. Example: See that guy over there with the twitch who one minute is sleeping in a heap by the parking meter and the next minute is lurching unexpectedly towards random strangers? Skitcher!
