A gentleman who considers it absolutely no bother to consume 6 litres of vodka over a music festival weekend. Whilst it is unlikely that a "6 Litre Joe" would consume the vodka straight from the bottle, it is perfectly feasible that he would fill up a pint glass with equal measures of vodka and mixer.
Bish: "Ooooftt whit! That boy in on his sixth litre of vodka in two days"

Marco: "Aye san, i've been watching his progress- he is a 6 Litre Joe if ever I saw one"
