"Inchon" is a word used to describe the act of hooking a finger into another person's body orifice, typically their nose, ear, or mouth. This act is generally seen as disrespectful and invasive. Synonyms for "inchon" include "finger hook," "digit insert," and "orifice intrusion." However, it is important to note that these terms carry similar negative connotations and should not be used to describe any kind of non-consensual or violent behavior. It is always important to respect personal boundaries and obtain explicit consent before engaging in any kind of physical contact with another person.
