biff

somebody in the military or cadets who can't be asked to put in much effort, sits out on things or is injured so can't do much or just can't be bothered to fo things properly but it's not really offensive and can be used jokingly 😂

"I can't do the marching my leg hurts so I'm going to have to bumble"
"Your such a biff!"
