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 3: Nothing else to do in this scumbo town

Get the Swinging Pig mug.
noun. This is used to descibe a drunkard who does nothing all day but sit around and consume alcholic beverages. It also helps if said person is a fat bastard.
Jason and Tom are so lazy, they are the biggest porch swinging liquor pigs I have ever met.
