I mostly mean it to be people who try to push for "team events" or "team lunches" or "team happy hours", even when some or most of the team make it clear that they're not interested. Often this is accompanied by shaming/annoyance if you're not interested in joining in.

I don't mind people trying to make friends at work, and often I don't even dislike the people who annoy me like this, I just don't like them as much as they seem to like the idea of spending time with me. There's a gap between people I like making smalltalk with before a meeting or while I'm taking a break to get coffee, and people I want to have a dedicated social time with.

If you want to make friends at work, don't use the mechanisms of my employment to coerce me into spending time with you.
