Since metal cardbots dont have mouths they can't kiss normally. I think that wild cardbots would just bonk their heads together gently to show affection, or brush up against eachother before moving on. Sort of like how cats just rub up against you and get angry when you dont let them. Imagine Tachi just throwing herself at Soleil, and she gets squished lol
Metal Cardbots just make a little "bzzt bzzt" against each other's mouthplates as a "kiss." I think since they're much more industrial vs. nature-oriented compared to Wild Cardbots, their customs are more conservative.
