인싸 [ inssa ] & 아싸 [ assa ]
These newly coined expressions are actually from English expressions. 인싸 is the abbreviation of 인사이더, which is Korean spelling for pronunciation of ‘insider’, and 아싸 is the abbreviation of 아웃사이더 ‘outsider’.
However, 인싸 and 아싸 are treated more as new words since the meaning of each is meant to be a little different from 인사이더 or 아웃사이더.
인싸 is a type of person who gets along with people, knows almost everything related, and works/participates with passion within the group that they belong to.아싸 is a type of person who loves being alone enjoying one’s own world rather than trying to be involved in a group.
These used to be used as a criterion at the very beginning of their history. For example, if you know 인싸 and 아싸 correctly, you are 인싸.
** If the person is deeply 인싸, the person is 핵인싸 (핵 [ haek ] means ‘nuclear’ or ‘core’).
