Looking for Japanese onomatopoeias that are linked to subcultures

Hello everyone, I hope your having a good day/night.

I'm a linguistics student in a sociolinguistics of Japanese class. I'm currently working on an essay for the class about Japanese onomatopoeias however I want it to focus it around slang and subcultures for things such as fashion and life style subcultures. I have lived in Japan and do speak the language are a very basic level, however I'm having a bit of trouble coming up with words to focus my paper around because I don't really know what to look for lol.

For example a word that I am defiantly using is ぴえん. In recent years its been heavily linked to Jirai kei fashion and aesthetics.

My question is basically, can anyone please give me some other onomatopoeias or slang that are heavily linked or associated to subcultures in fashion, lifestyle, or really anything (that is appropriate for a uni paper lol).

Thanks so much!
