Upon spotting a dumpster on wheels (Tesla Cyber Truck) you exclaim "Cyber-Slap" while swiftly smacking a friend upside the back of the head like a Japanese comedian duo.
Similar to the old "Punch Buggy" game.
PERSON A: "Cyber-Slap!!" SMACK!!!
PERSON B: Oww! That hurt m'fer!... but my head now matches the pain in my eyes from that ugly piece of shit, so fair enough.
