The nasty liquid at the bottom of a garbage barrel that smells like curdled milk and feces. Usually brownish in color and has a tendency to drip on one's feet.
Bin Juice is a player - usually a Rugby Player - on a team who never gets picked. They remain on the bench the entire time and somehow never find their way onto the field to play. They are the bottom of the barrel in terms of players. They are the Bin Juice.

"No way mate, he's total Bin Juice."
"Coach just told me I've got a lot of 'work ons'."
"Oh mate, sounds like he just crowned you King of the Bin Juice."
