Players in the game Sea of Thieves that participate in an alliance and queue up for an activity, the Ship Swappers are those that wish to leave a specified event and effectively jump the queue in transferring to another ship of their choice.
That dirty ship swapper wanted to leave Merchants for World Events!
I once knew a ship swapper, they went home with the first dirty Sea Dog to offer them a spot on their bowspirit
The galdem don't swap ships...
