Chad: The earth is flat ya know.
Neil: You know that it has been scientifically proven that the Earth is round, right?

Me: Chad's awfully quite.
An unfortunate (and all too common) misspelling of the word quiet. This usage originates from cheeky gits attempting to parade their self-affirmed expertise regarding the latest 133t computer hardware. Examples are most often found in customer-submitted reviews of equipment such as CPU coolers, graphics cards, power supplies, water cooling systems, and most commonly, case fans.
Instances of the term actually should prompt product re-evaluation in sensible folk, as users of it call into question whether they are capable of critical thought, or if they even own said equipment.
