an expanded version of gtfo, but useful while driving or walking.
You know when you are trying to get into a door, and another person is trying to get out, and you try to let them pass you on your left, but they try to let you out that same way, and then you do the same thing on the other side? After that I just yell GTFOTW!
Spawned from the ashes of the ROFLcopter, the GTFOGRENADE is used for kicking or banning idiots from your IRC channel or banishing scrubs from your base. Founded by silencer of Team Exile.
