To me, just that statement reads like collecting something, being proud of it, and wanting to start a conversation or find shared interest in it rather than some competition. Maybe I'm lacking context?
I guess it's bordering on being literal poison. Chilli peppers have evolved specifically to be inedible by mammals. So I guess being obsessed with hot sauce is not a toxic trait per se, but it's in the neighborhood.
More seriously though, I love spicy food, but not all food is supposed to be spicy. Leave other favours room to breathe as well.
So I think I know what you're talking about, but I don't think having hobbies is the issue here.
You do see this a lot when guys are talking and someone brings up a sort of niche hobby (tech, fan bases, something that requires a lot of knowledge)
Guys will all show interest but not want to be talked down to or mansplained to on a topic they're passionate about (yes ladies we experience it too)so they overcorrect and try to prove their knowledge real fast.
This sometimes leads to a sort of feedback loop where the other person thinks they're trying to one up them and tries to be the more knowledgeable one and on and on, I've seen so many guys do this, that's why I avoid talking about hobbies with IRL friends (looking at you RuneScape)
