braggadocio

"Fink :american frontiersman and folk hero known for his marksmanship, fighting skills, and braggadocio."

以枪法、斗技和吹牛而出名美国拓荒者和民间英雄.

In the end, there might be some signs that boorish boys know they're overreaching — and that may be expressed in the level of their braggadocio.

后,也许有一些粗俗男发现自己过了头迹象——这表现在他们吹牛程度中。
