There is a movement at Wayne State University in Detroit, Michigan, which I once visited, to “bring a collection of old school words back into the modern-day vernacular.” They are:
Caterwaul – A shrill howling or wailing noise.
Concinnity – The skillful and harmonious arrangement or fitting together of the different parts of something.
Flapdoodle – Nonsense.
Knavery – A roguish or mischievous act.
Melange – A mixture of different things.
Obambulate – To walk about.
Opsimath – A person who begins to learn or study only late in life.
Philistine – A person who is hostile or indifferent to culture and the arts, or who has no understanding of them.
Rapscallion – A mischievous person.
Subtopia – Monotonous urban sprawl of standardized buildings.
Caterwaul and philistine I use as often as possible, myself.
