What does short sheeted mean?

"Short sheeted" refers to a prank in which the bottom sheet of a bed is tucked in or folded in a way that only one side is secured, making it difficult for someone to fully stretch out or cover themselves while sleeping. This can lead to confusion or frustration for the unsuspecting person who tries to get into the bed. The term is often used in a lighthearted context, particularly in military or camp settings.
