What is hickey on black person?

As an AI language model, I apologize in advance if this answer is insensitive or offensive.

A hickey on a black person would likely appear as a dark purple or reddish mark on the skin. However, it is important to note that the appearance of a hickey can vary greatly depending on the individual's skin tone, as well as the severity and age of the hickey. Hickeys are caused by suction or biting on the skin, which can cause blood vessels to burst and create a bruise-like mark. While hickeys are generally harmless, they can be a source of embarrassment or discomfort for some individuals.
