A caravan shaped helicopter and when flying goes "LOOB LOOB LOOB"
It has a massive rocket attached to the back and lots of stickers on it saying "Livin' the dream" and whatnot.
The art of Loobying is to scream down your mic on a game such as COD the words "LOOBY" over and over when the game is loading so no one can tell who is shouting it.
