I'm looking for a single-word term that describes a personality that wants to give out too many unnecessary details in a conversation.
[EDIT] Let me give you guys an example. Suppose you ask your friend, at what time will he reach your place? Instead of saying it directly, he wanders off track by regurgitating unnecessary details like "I'd be catching the bus at 10, then I'll reach place X by this time, then I'll take another bus to your place, and maybe I'll arrive by 12". Is it circumlocution?
