The fictional item that a drunk womaniser (see Leslie) will brag about. something that is usually a bit far fetched. He may promise a day out in the speed boat he doesnt own, or to go riding on the horses he doesnt have. This is all in the interest to bed the fat mess he is trying to impress.
The term derives from the shamed childrens tv presenter "john leslie" who was a mass womaniser and said anything to bed his chosen ladies.
Friends mock "quickly, the the leslie copter! (in the style of batman or robin)

Man, billy is wasted. He's off promising the world to that bird. He's so desperate hes telling her about the "leslie copter"
