term among Airport
personnel, for the luggage handlers
if you look out the window of an Airport, or airplane, you see the guy driving a small tractor-looking cart, pulling several trailers of luggage. They open the Airplane's cargo hold and deposit/remove baggage. The name 'throwers' evolved because, well, they don't exactly place the bags on the plane, even the fragile ones.
According to Fight Club, throwers are the ones who call the police/ bomb squad if they find a vibrating suitcase. They usually ignore the ticking ones because modern bombs don't tick.
But the vibrating ones, 9 times out of 10 it's an electric razor inadvertently switched on, but every one time...it's a dildo. Of course, the airport never implies ownership, never your dildo, always a dildo. Sometimes even the owner of the suitcase is a male.
