To me it would be more a roll than a bap or a barm, but they're almost synonyms. The weird one for me was when a mate insisted it was a teacake, and I suggested that would only apply if it had raisins in it. What I was describing, he insisted, was a fruit teacake, and without fruit it became a teacake. This is contrary to what the rest of the country believes outside of North Manchester, but has become a running joke for many years between us.
