At the drop of a hat

Thành ngữ này đã xuất hiện từ những thập niên 80 vào cái thời mà người Mỹ rất thích hay đội nón, và trước khi khởi đầu một cuộc chạy đua, họ phải vứt ngay cái nón xuống đất để chạy cho nhanh. Chính vì thế nghĩa của cụm thành ngữ này có nghĩa là "làm điều gì đó ngay tức khắc mà không bị ai xúi giục hay bắt buộc".

  • do it suddenly and easily, often without any preparation
