Humans have superstitions like black cats causing bad luck and throwing spilled salt over your shoulder to prevent (again) bad luck. Do Cybertronians have any superstitions like that?

Flying upside down will fry your neural circuits. Don’t walk backwards when both moons are visible. Don’t think about touching your spark while travelling through a tunnel, and if you have to fly over a body of water during the dry season, by all means don’t hum to yourself. Eat silver dishes around the middle of the year if you want credits to come your way; gold for good health; quartz if you want to reunite with old friends. An itch in a seam you can’t reach means someone is talking about you.

Spit on your tires for good luck. If you’re in Tesarus, spit on a friend’s tires.
