Helicoptering: equivalent of planking/owling/etc. Contrive to suspend yourself or appear suspended in midair, out of alt, flailing arms in circles. Bonus points for grounders overcoming the subspecies-wide fear of heights to helicopter in high places. No image manipulation around! Also funny if done by actual helicopter-mech while not in helicopter mode.
Wormholing: equivalent of horsemanning (old human thing of looking like you’ve been beheaded). Appear to be halfway through a wormhole, i.e. conceal everything below one’s waist and have a friend conceal everything above their waist. Made trickier by the massive size differences possible between Cybertronians.
Combining: stack on ur friends and attempt to walk like one giant person
a thing that’s basically dabbing but w/ legs and/or wings
