I think it can happen from most of your options.

Idr connecting with anybody over anything banana related.

Obtaining a friend is easy, maintaining that the friendship requires effort on both ends equally.
I've made a lot of friends, but I would only call about 4 of them IRL true friends.
I'll be at their place picking up the mess from a storm, taking my snow blower to their place cuz they dont have one, bringing over beers and food for a hang out.
I know they'd do the same.

They call that friends with benefits
