Christchurch: It's Munted
While definitely not averse to using such words as fuck and cunt, modern New Zealanders take great delight in reliving the stultifying drudgery of the 1950s and will often be heard to utter (at least ironically) the phrase "Oh, Christchurch!", especially when tripping up, falling over, climaxing, etc.
