Boro briefcase 

A carrier bag that "poor peoples" shops give out ie: Aldi Liddle Farmfood and so on. Young poor children often are riddiculed by the better classes at school for bringing books etc in the aforementioned boro briefcase in the Middlesboro , Billingham & Stockton area.

Also what scummy piss heads carry their "pop" home in. Slightly more discerning scumbags keep Tesco or Somerfield bags on them to tranship the adli booty into, so they dont look quite as scummy on the bus home!

Eyup Dave! ere comes raggy Richy with his cans in a "boro briefcase"
