A condition, usually resulting from long hours sweating, sitting, and accumulation of Production dust, in the nether regions of one's gluteal cleft, i.e. generally being a technician. Other terms include: Monkey Butt, or that "Not-So-Fresh" feeling. Remedies Include: 1. A shower. 2. A blower nozzle inserted into the waistband of your pants. < Caution: Only provides temporary relief, may create toxic environment for co-workers, and can be mildly addictive.> Preventative measures include: 1. Wearing looser fitting pants and underwear. 2. Proper personal hygiene. <This is not an inoculation--it is only a delaying tactic. Monkey Butt is, eventually and sadly, unavoidable.> 3. Application of an over-the-counter remedy such as Duluth Trading Company's Anti-Monkey Butt Powder. [Lighting programmers and audio engineers swear by Gold Bond Medicated Powder, but always warn to use only the Yellow. The Blue is for FEET ONLY!] Seriously, Monkey Butt can lead to other, very uncomfortable, health risks and should be taken seriously, well, not too seriously. Similarly, as Lt. Dan said to Pvt. Gump, "Change your socks. Always have dry socks."
