Top definition
A young professional who looks and acts many years beyond their tender age. Usually sucking all the fun out of situations which involve banter, good chat, LAD Soc, jokes, repartee, and tomfoolery in a fashion that can be compared to that of a fire safety blanket. Office work may also require this individual to become a social hermit at certain times of year. A receding hair line is a prerequisite for this title.
