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!'
When the proud proprietor of a large boner pulls his cock to the side only to let it go a moment later so that it swings back assaulting the victim's face.

"That bitch didn't know how to give head, so I lumberjacked her face with my cock."
