Oh, hell. The boring guy and the loudmouth?
该死 那无趣男和那嗓门吗?
A " loudmouth" (loudmouth) – one word – is, as you might guess, a person who always talks very loudly and often too much, someone who perhaps tries to impress other people by bragging, by saying how good he is.
“嘴巴” (loudmouth)——一词——正如你可能猜到的那样,一总声说话而且经常说得太多的人, 一可能试图通过吹牛、说自己有多好来给别人留下深刻印象的人。
