Random as in "doesn't make sense with the way [you] present [yourself]"? If so, I don't think I really have any hobbies like that. I mean, I listen to emotional music but I don't want to sound like the "Crying to Phoebe Bridgers in the shower, I'm so babygirl" guy. Another would be watching commentary YouTubers, maybe ... Or watching The Group, but that's mainly a thing within my friend group. If it's random as in "any", then listening to music and sitting there reading the lyrics like I'm reading captions on a movie (/Ref)
