When three or four individuals walk side-by-side down a place of public passage, such as a small alleyway, taking up unnecessary space and often causing annoyance to passers-by coming in both directions. Often done by uncouth teenagers or slow-walking old age pensioners. Named after the characteristic walk of the main characters in the film "Ghostbusters" or the cartoon show "The Real Ghostbusters."
Chav 1: Hey guys, here come some ghostbustin' grannies, this alley aint big enough for the both of us.
