Scare your villagers with a stink bug sword.
The Flymeal is the stink-bug sword: craft it at honey (the crafting liquid, stand by a honey pool) from a Gold or Platinum Broadsword plus 5 Stinkbugs. Uniquely, it can hit town NPCs - whack any villager once, cue fart noise and the Stinky debuff, achievement popped. No villagers seriously harmed; dignity not included.
