One example is the ever-present cry of "dongsuan" (literally "frozen garlic") during elections of all kinds in Taiwan. Dongsuan is a corruption of the term "dangxuan" -an exhortation that one's candidate is a "sure thing" in an election-that originates from the pronunciation of those same characters in the Taiwanese Minnan dialect.
流行語多是約定俗成，只有生活在當時當地的人，才解其中況味。台灣每逢大小選舉，不絕於耳的「凍蒜！」
