balatron
A buffoon; one who speaks a lot of nonsense and is characterized by self-indulgence.
If we are "students of the Balatronic dialect" — a dialect so called from the "Balatrons" or professional buffons who invented most of it — we shall perhaps refer to its users as: — "Blunderkins, having their heads stuffed with nought but balderdash.
Where it comes from
From Latin balatrō (“jester, buffoon”). Cognate with Galician baladrón, Spanish baladrón, both meaning "braggart".
