[誤] He has always got a hard mouth and never admit a fault.
[正] He never says uncle.
注:say (cry) uncle: to give up or in; to surrender; to admit defeat. Mainly used by boys, as when fighting。
主要是男孩們打架時的用語,當一方想制服另一方時,就用命令的口氣說:“Say uncle!”這時,有的孩子為了表示不服輸,就是不說。后來,say uncle 就成了“服輸”的代名詞,而 not say uncle 就相當于“嘴硬”了。
