Etymology

From คืน ‎(kʉʉn) +‎ หมา ‎(mǎa) +‎ หอน ‎(hɔ̌ɔn), literally "dog-howling night".

The term originated from the practice of electoral frauds in Thailand. On the night before an election day, political party agents usually visited people's houses to give money to voters, intending to buy votes for the last time. As they came in a suspicious manner, watchdogs became very noisy that night.
