unwashed

He was unwashed, uncombed, with his clothes half buttoned.

他蓬头垢面且衣衫不整。

He smelled offensively unwashed.

他很脏，散发出难闻。

The boys in their grubby navy bow ties and blue uniforms were indistinguishably horrid—nose-pickers, thumbsuckers, snorers, neer-do-wells, farters, burpers, the unwashed and unclean.

着肮脏海军领、穿着蓝色校服男生无一例外地令人恐惧——挖鼻子、吮手指、打鼾、不干好事、放屁、打嗝，穿衣服不洗，邋邋遢遢。
