Examples:
Freemasons use intricate grips and pressures
College fraternities often have unique handshakes with hidden gestures
Resistance groups during wartime used subtle touches to confirm identity
👉 In these cases, the scratch isn’t romantic — it’s strategic recognition.
3. An Unconscious Habit or Nervous Tick 🤷♂️
Sometimes, it means nothing at all.
The person may have a habit of touching palms more than usual during greetings.
Could stem from anxiety, excitement, or simply not realizing they’re doing it.
If repeated with many people, it’s likely not intentional or symbolic.
Context matters: Is it only with certain people? Does it happen with eye contact or a smile?
4. A Sensory or Neurological Response 🧠
Some individuals are highly sensitive to touch (a condition called synesthesia or heightened tactile awareness) and may respond instinctively to skin contact.
They might stroke the palm due to an unconscious sensory feedback loop
