Someone who annoyingly waits to begin typing until they find all the letters in the word they want to type, then types them in a single, annoying burst. Gives the typer a false feeling of skill; irks observers.
Becoming consigned to oblivion as those who can't type are being weeded out with old age.
Stanly typed out the word 'irritating' so fast that he thought we was impressing everyone around him with his typing speed. In reality, everyone knew he was a fusillade typer and spent 15 seconds looking for the keys before he began typing.
