In the Royal Australian Navy, a Sea Squarey is referred to as another member of the ship that an individual is "squaring away", which in laymans terms means to involve in carnal knowledge, in the roughest possible sense.
Did you hear that Nato just got charged for pumping his Sea Squarey in the ship's laundry? It was a massacre of sweat and screaming.
