A 'high sign' refers to a prearranged signal, often subtle, used to communicate secretly. Think of it as a nonverbal cue β a secret handshake, a specific phrase, or even a wink. It helps people coordinate actions without alerting others. It's similar to code but relies on visual or auditory cues. High signs are frequently used in teamwork or situations requiring discretion. The intent is to convey a message without explicitly stating it. It's like having your own personal language with someone.
