Caps Lock Voice 

When a normally calm person has to raise their voice and use an authortative tone. It is the equivalent to using the caps lock key in the digital world.

Sara tried to get an attitude with me yesterday and I had to turn on my caps lock voice and put her in check.

Chris was being run over at work, so Jason told him it was time to turn on his caps lock voice.

CAPS LOCK

A key on the keyboard that tweenie girls, newbies and the mentally unstable insist on pressing and using for their entire forum post/IM/text message for reasons unknown.

Perhaps they think it looks cool, or maybe they can't do joined-up writing yet and write in block capitals.

It is the most annoying button in existence.
