Whopperjawed

Definitions

"The fact that inexperienced, ignorant men have often been induced by the advice of mere theorists, or their own over-confidence, to undertake this kind of building, resulting, as might naturally be expected, in ungainly, crooked, whopper-jawed, and cracked walls, is no evidence whatever against the system, but only an evidence of the folly of men, in undertaking what they don’t understand."
