Common expressions

  • なめくじに塩(しお) — putting salt on a slug (describes someone who shrivels up or becomes timid, often from embarrassment or fear)

The expression なめくじに塩(しお) is used figuratively to describe someone who shrinks back or loses confidence, similar to the English "like a deer in headlights" (though the nuance is different — it emphasizes shrinking rather than freezing).
