Informal/abusive term for Popstarz, a "gay alternative" club night running in
London since 1995 and which nowadays attracts a varied crowd including indie kids, emo kids and other scene kids as well as older men and women.
It refers to the contingent (hopefully a minority) of slags who attend and the occasional, partial atmosphere of a meat market for
college and university kids in which some sink, some swim and others feel as though chucks of flesh are
ripped out of them.
Also derivative verb to popslag (see below).
