A backhanded compliment, also known as a left handed compliment, or asteism is an insult that is disguised as a compliment. Sometimes, a backhanded compliment may be inadvertent. However, the term usually connotes an intent to belittle or condescend. [1]
A backhanded compliment may fool the listener, but the compliment remains "backhanded" because the speaker is being intentionally slighting and insulting. In some cultures, backhanded compliments are considered a genteel or polite way of expressing disdain.
In each instance, there is an initial compliment: praising a piece of clothing, a person's intellect, a person's driving ability, or a person's looks. However, each instance also includes an implied criticism: the person's figure desperately needs improvement; the person appears unintelligent on the surface; women don't drive well, and therefore any skill at driving is noteworthy; the person at some point looked unattractive.
