history
From 《论语·微子》 (Analects, 'Weizi'): 我则异于是，无可无不可 — 'I myself am different from these [recluses]: I am not committed to any one course, nor ruled out of any.' Confucius contrasting himself with rigid hermits; he chooses based on what is right, not on any fixed rule.
usage
Today the phrase is everyday Mandarin for 'whatever, no preference.' Note the literary structure: possible (可) and not possible (不可) both negated — 'not insisting it's okay, not insisting it's not okay.'
