I'd say roll with whatever name comes first, as you can always change it later. Dwelling too much with it can be a sign of perfectionism.... or procrastination, or ADD.... or just in-experience.
As I got older and had more experience "naming" things stopped being a problem, as I always knew I could change things later on, and trying to be perfect on first shot is futile.
Thinking of programming as an essay that will need some editing/revisions when done, helps a lot.
-- I will take "things i will never do" for a 100 Alex.
In this one specific example being paralyzed about naming something is silly.
Another thing I do sometimes is tricking people into talking about the thing I'm trying to name without giving away that I'm looking for a name. They often just use the natural term I couldn't think of.
