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.
