Lingerers, yes. Perhaps I slightly misused the term.
You know the guy at the party who is the last to leave? He doesn't seem to get the social cues like others, so he stays well beyond what is comfortable. Often people will sense a turning point in the vibe of the party and leave en masse. For some reason he doesn't. Perhaps he wants to ask you something? Or maybe he likes you? Who knows. Now it's getting awkward, but he's still here.
That's kind of what I was thinking of.
Edit: Another literal interpretation that isn't strictly the definition is the idea of the people who "hang on" to an idea and just won't let it go. Hanging on to it well beyond its useful lifespan or relevance.
