A hicky is a red or purple mark left on the skin, commonly caused by sucking or biting during intimate moments. However, some might find this term inappropriate and prefer to use other synonyms to describe the same thing. One such term is 'love bite,' which is a commonly used term for a hicky. Other alternatives include 'passion mark,' 'suction spot,' and 'neck bruise.' Still, others might use 'memento' or 'souvenir' to describe a hicky as a reminder of a passionate moment. Regardless of the synonym one chooses to use, it's important to remember that consent is significant when it comes to intimate moments, and anyone who gives or receives a hicky should do so willingly.
