White elephant

The phrase "White elephant" typically refers to an object, project, or possession that is expensive to maintain but has little or no practical value or utility. It can also refer to something that is difficult to get rid of or has become a burden due to its cost or maintenance. The term originated from the practice of the kings of Siam (modern-day Thailand) gifting rare albino elephants to courtiers who displeased them, considering the animals sacred and valuable, yet challenging to care for. Today, it is commonly used metaphorically to describe any unprofitable or burdensome possession or undertaking.
