What is tie sign?

A tie sign is a nonverbal communication gesture or signal that individuals use to indicate or show their affiliation or connection with a particular group, organization, team, or ideology. Tie signs can take many forms, such as wearing a uniform, displaying a badge or insignia, using specific jargon or symbols, or making a distinctive gesture or posture. Generally, tie signs are intended to communicate a sense of belonging and conformity within a social group, and to create a sense of identification and trust among members of that group. Tie signs can also be used as a means of asserting authority or status within a group, or to signal loyalty or allegiance to a particular cause or ideology.
