This salute has expanded beyond simple fan culture to mean things like "I respect your opinion" or "Good luck," acknowledging and blessing the other person. So, you can use it to send a unique yet warm message of support.

This hand gesture has an interesting backstory: actor Leonard Nimoy was inspired by a gesture he saw in a Jewish ritual during his childhood. It holds the deep meaning of wishing peace and well-being, "Live long and prosper," so it's used not just by fans but also to show respect and blessings.
