Passenger, often inexperienced flyers in Kettle Class
, who crowd around or line up at a gate at an airport completely blocking the boarding area and preventing First and Business Class passengers from being able to get on the plane when they're allowed to. They can also cause delays and confusion if a passenger in a wheelchair needs to board as the chair has to plow through the mass of gate lice hovering around the gate.
When it's time to board, they have to be shooed from the front boarding area to the back of the line, delaying the flight for everyone.
"We should probably head to the plane early before the gate lice show up".
"I don't understand why those people were being gate lice. Don't they know Zone 4 means you board last ?"
