@tomie objectively, a bow. I tend to give handshakes if it's formal. I'll bow my head or give a small salute informally though.
@tomie i'm not sure how it would go in other places, but it's not much of what comes to mind when you think of a salute really either.
hard to explain with text but i basically put my index and middle finger around my eye/temple and then flick it forward in a saluting motion. "salute" is just the closest i can think of in a single word lol.
i have no idea where i picked this up.
@tomie wait does kakashi do it
@tomie i can't find video of him doing it specifically lol but you're probably right xD
@beardalaxy definitely anime
