adjective/possible noun to describe someone believing themselves to be very cool but in fact rather common and following the crowd. Usually inhabits London's fashionable East End sporting carefully battered cowboy boots, quirky haircut and well-rehearsed bored look. Could be beautiful but blighted by miserable demenour, as if working in a chippy. Often accompanied by shoreditch twat.
'She think she so cool but she just Hoxton chipshop to me!'
