Suzie

In the Jamaica Combined Cadet Force, "Suzie" is the name given to a cadets girlfriend, wife etc.
As the saying goes "All for one and one for all", higher ranks often joke about a cadets girlfriend wanting to share a cadets girlfriend, wife etc.

Sergeant: You lad, do you have a girlfriend?
Cadet: Yes sergeant

Sergeant: Well, that's our Suzie now
