The term "kissing kin" usually refers to a close relative who one would feel comfortable kissing, such as a sister, aunt, or cousin. However, there are many other words that can describe relatives who are just as close. For example, the phrase "blood relation" indicates a family member who is related biologically, while "family ties" suggests a strong bond between relatives. Other synonyms for "kissing kin" include "kinfolk," "kin," and "family members." Related terms might also include "clan," "tribe," or "lineage." Regardless of the term used, it all boils down to the special connection shared between family members.
