A dozen 一打，是十二的意思。如果某人“talks nineteen to the dozen 从十九说到十二”，这个表达的实际意思是说话语速很快。就好比在说十二个词的时间内说了十九个词，让听的人不知所云。
Sorry, when I’m nervous I talk nineteen to the dozen.
I can’t understand my lecturer at all. He talks nineteen to the dozen. Someone should tell him to slow down.
It was a terrible first date. I talked nineteen to the dozen about my ex-girlfriend.
另一个和说话相关的表达是 get a word in edgeways，意思是“插不进话，插不进嘴”。
She’s such a chatterbox that once she starts it can be difficult to get a word in edgeways.
There were so many people asking questions after the lecture it was difficult to get a word in edgeways.
