A short time span where one voluntarily does NOT shower or shave. As you are NOT needing to be anywhere or meet anybody, you just let yourself go and be free!
Roger: Hey, Dave! How was your three day holiday? You did not have to go anywhere, right?
Dave: Oh, Man, it was great! I did not have to shave or shower, and all I did was watch playoff football and eat pizza! A hygiene hiatus like this was perfect!
Not wanting to shave or shower for a short time. This usually occurs during 3 day holidays, as well as particularly during short stints of inclement weather.
Roger: Hey, Dave! How was your Present's Day holiday? You were off for 3 days, right?
Dave: Man, it was great! I watched a LOT of hockey, and the best part was not having to shave or shower during that time. Once in a while, you just have to let it all out and have a Hygiene Hiatus!
