More Rumble headcanons because I think you all understand my motivations by now
(also pls don't be afraid to DM me questions about hcs or even just random thoughts if u enjoy the cassettes pls I don't bite, the only thing I do bite is the bars of my enclosure I'm Told)
Rumble headcanons on earth things!
Clothes! While at the decepticon party (human party thrown for "decepticon day" ) rumble noticed the various attire people wore to the party, and started taking notes on some of the things the humans he's had to beat up have worn in various settings.
Some clothes make him wonder why you'd even do that to yourself. Like..is that not itchy? While other clothes have made them heavily consider trying to get some in their size to try out. He won't wear form fitting clothes when he first tries it out (he's worried about sensory issues with the organic fabric hugging his plating. But as he tests the feel of different fabrics out he'll get more comfortable trying more form fitting clothes. (My headcanon for basic G1 rumble in regards to this is that he'd definitely put the clothes on wrong and get himself stuck)
Music! Honestly he's welcome to trying every genre once or twice! Just be prepared that if ur a diehard for smthin it better be a banger because if he disagrees with you in a "hell no" way then ur tusslin (love whatever music u like but if yo swearing on ya mama that it's good be prepared to hurt yo mama if u trippin) he likes slow but also fast paced songs! Definitely takes some of the beats and tracks from human songs and remixes them with Cybertronian music sometimes. I feel like he's more of a reverb daycore person then a nightcore one tbh
Dances! He's got a catalog of dances he knows (he may hang out with jazz to much to that objective degree but ssh) but he also studies human dances. I can't see him doing tiktok trend kinds though, but if you're in his circle and you wanna teach him he'll give you a klik or two to try and catch his interest.
Overall thoughts? Humans are interesting. Shorter lifespans which kinda sucks in their opinion, but he don't really sway either towards good or bad in regards to the entirety of humanity. He has no reservations on beating a human or two to a pulp if they get in the fraggin way. (He finds the fact their heads break very similarly to fauna they eat very ironic yet also hilarious) yet I won't say he can't also make friends or have dynamics with humans too. Frenemies, friends, unlabeled n fantastically strange in only a way rumble can, etc!
Food! I feel like he tried soda first due to how often it's advertised and how common it is to see it just about everywhere. Also the idea of bubbles...(would be the type to stare in horror when someone drinks something that's gone flat) however scrubbing the sticky syrup out of their internals was less then pleasant...still can't resist sometimes though even if he grumbles about the mess later.
Ps. He's not immune to getting things stuck in his helm for random reasons even though he only heard the thing twice!
