这个聚会的一切都过了头而且愚蠢：乐队，气球和纸帽子。

Everything about the party was overdone and silly: the band, the balloons, the paper hats.

《柯林斯英汉双解大词典》

《牛津英语词典》的解释最恰当：“一个木制的头，戴帽子或假发的木头，因此，这种脑袋中放不下才智，含义为愚蠢的人。”

The OED puts it best: “A wooden head, a wooden block for hats or wigs; hence, a head with no more intelligence in it than one of these, a blockish head.”
