Hickeys

Hickeys are a sign of young love, or at least of young sexual excitement. The medical term for a hickey is erythema, which means: a reddened area of skin caused by dilation (expanding) of the blood vessels.

Another official name for a hickey is hematoma, a small collection of blood beneath the skin due to broken blood vessels. So basically, hickeys are just bruises that occur on the neck.
