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.

An aggressive, or excited attitude characterized by its loudness. The term originates from electronic communication. Sentences and words spelled with the Caps Lock button turned on --in other words, all upper-case-- is the modern written equivalent of shouting at someone. It usually signifies anger, or sometimes intense excitement.
Kelly looked at Lisa incredulously. For a moment she was speechless. "WHAT THE HELL?! HOW COME YOU CAN'T MAKE IT TO JAKE'S BIRTHDAY PARTY?!" Lisa, startled by Kelly's shouting, replied, "Why you gotta get all caps lock on me?!"

Caps. Lock is a key on your keyboard located directly to the left of your 'A' key. As you know, capital letters are used for expressions that are meant to sound like they're angry or yelling, but, however..People abuse the use of the caps lock key and capitalize all of their letters to either sound excited or to be noticed. This is why a small organization has created a rule against caps lock being used for anything but the purpose for which it was created. This, is for three reasons.

1) It's incredibly obnoxious to read.
2) You just seem like you're angry all the time
3) There is no way for me to read that except for in a yelling voice.
PEOPLE WHO TYPE LIKE THIS ON EVERY SINGLE STATUS ARE INCREDIBLY ANNOYING AND NEED TO TAKE A TYPING CLASS IN WHICH THEY LEARN TO NOT ABUSE CAPS LOCK.
