A deliberately non-sensical parting farewell, popularised in the TV programme 'Nathan Barley'. It approximately means 'see you later' and 'don't take life too seriously'.
(at end of conversation)

Nathan Barley: ...alright then mate, keep it foolish, yeah?

Julian Barrat's character: what does that even mean?

Nathan Barley: erm...

Julian Barrat's character: Just fuck off.
