Hand someone a lemon

The phrase "hand someone a lemon" is an idiom that means to give someone something that turns out to be of little or no value, often disappointing or unsatisfactory. It draws upon the symbolism of a lemon, which is sour and undesirable to taste, representing something undesirable or defective. When someone hands another person a lemon, they are metaphorically giving them something that doesn't meet their expectations or needs, leading to frustration or disappointment.
Furthermore, the expression can extend beyond physical objects to include situations or experiences that turn out poorly or unfavorably. For example, if someone invests in a business opportunity that fails to generate profit or if they purchase a faulty product, they may feel as though someone has handed them a lemon. The phrase conveys a sense of being deceived or misled, as the recipient realizes too late that what they received is not what they had hoped for or were promised.
