A pub in Rockingham, West Australia, that is frequented by naval personal (especially pay day thursday) and young mothers looking for a daddy for their bastard child. Swinging pig is derived from 'rocking' and 'ham'.
Be aware, fights in or outside the pub are almost a given every Thursday night, with bored locals meeting up and fighting for no reason.
Guy 1: U going to the swinging pig tonite?
Guy 2: Shiit.... do i have to?
Guy 3: Nothing else to do in this scumbo town
