This word is for all those people who have children or relatives that lay around their house all day or will not get out of bed on time. The child or relative must also understand instant messaging. You can now shout..."GUN." Repeatedly if you like. If you shout it loud enough and with enough conviction, it will scare them to death, or at lease get them to open an eye.

John, you lazy bum,it's 11 o'clock...GUN!...GUN!...GUN!
