躺着说谎用英语怎么说

"躺着说谎"用英语翻译为"lying down to tell a lie". 是一个英语俗语， 意思是借着躺在床上或是其他舒适地位置时说谎话。
举个例子：
"John was lying in bed and told his wife he had a headache, but she could see through his lie and knew he was really just too lazy to get up." (约翰躺在床上，告诉妻子他头痛，但她一眼就能看出他在说谎，因为他是懒得起床)
"I'm not going to listen to you lying down to tell me you're innocent." (我不会在你躺着时候相信你是清白的)
这个俗语可能来自于人们通常在躺在床上或者是其他舒适地位置时会有些懒散，不是很用心地说话,所以在这种情况下说的话更可能是谎言。
