Nasty is a village in an English region called Hertfordshire (they pronounce it herts that rhymes with something rude). If you are a stickler for detail then you’ll want to know that Nasty derives from the Anglo Saxon æt þǽm éastan hæge meaning “near a field with a hedge”. You can buy Nasty maps as souvenirs and possibly have a Nasty burger there. If you tease the locals you could get a Nasty surprise so try hedging your bets and being nice.
