can anyone explain to me what this expression means?
"I always look over my shoulder".
And also I have a problem with the proposition in this sentece;
can I say: "Am trying to put the meat in the boan" or;
" Am trying to put the meat on the boan"?
Without further context, I would say that "I always look over my shoulder" means the speaker tries to be careful in his daily dealings so that "enemies," perhaps business competitors or other rivals, don't have the opportunity to do him harm.
I don't know what a boan is, so I can't answer your second question. :)
