Caps lock voice refers to the authoritative and raised tone used by a normally calm and quiet person when he/she has had enough of someone or something. It is the equivalent to using the caps lock key in the digital world to show your strong emotion.

Caps lock voice指平时冷静沉默的人在对某人或某事忍无可忍的时候转而采用的一种提高了音调且颇有威慑力的说话语调，这种方式相当于在网上聊天时用全部大写的方式表达自己激烈情绪，所以，就叫“大写锁定语调”。
