Gownow is a term used when a person wants to play Gears of War with a friend. It can be used as a command or a verb. It is a cool sounding word, and as long as you don't define the word for other non-gamers, will make you seem cooler. If one texts with all capital letters, it places the "emphasis on execution."
James, Tom, Kevin! You know what time it is... Gownow!
