A large bag of alcohol (typically wine), generally very cheap, rancid on the palate and
housed (temporarily) in a box. Typically a lower socio-economic choice of beverage.
Often followed by violence upon or by the person consuming said
flagon.
NB:
Flagon can be inflated post-consumption to provide a pillow. Nice.
"Hey
Morton you
dardy mutt, come aroun' to our place and bring a flagon of woobla.
Der's a party happening tonight"
