When one is writing on a forum,msn,facebook...etc and does'nt relise that he/she has left caps lock on and posts, then notices that he/she has wrote the whole thing with caps lock on...

An ache or pain located in the head caused by reading and writing in continuous caps lock, it happens because when you read caps lock it is like you are shouting over people, that arn't actually there.

There is no cure.

To shout at someone unnecessarily.

Shouting at someone unintentionally, as if your internal "caps lock" was accidentally struck.

Typing or texting a message to someone, without realizing that the caps lock is on, and sending the message to the person in all CAPITALS

Also typing in all capitals to emphasize or "yell" over telecommunications.

V. The truncation of "bust a cap". Which is to "shoot" in urban slang.

"Bust a cap" is the current bastardization of a 19th century hrase in which a person would 'bust a cap', that is to say, bust the cap of their flint lock weapon.

A.K.A. Rich City, Richmond VA, the capital of tha ol' dominion. I'm pretty sure the name originates from the high per capita murder rate (usually in the top 10 in the country), hence a lot of caps are busted here(see bust a cap).

When you are talking on some form of chat, (messenger, icq, talk, chatroom etc) and you accidentally hit the caps-lock key and don't notice before sending the message. (Caps in chat means that you are shouting)
Analogous to how someone with Tourette's syndrome will randomly yell (and often swear) in the middle of what they are saying.
