What it means
To bimble is to wander about in a slow, easy, no-pressure way, usually with no real mission beyond being out and about. It’s very British and gently daft, the sort of word for a meander where the point isn’t getting anywhere fast, it’s just having a little roam and letting the day do its thing.
