Bimble …
No, not bumble. (Autocorrect didn’t get me this time.) It’s bimble …
As in, to bimble along.
(v.) walk or travel at a leisurely pace.
On Sunday, we bimbled around Spitalfields and Brick Lane.
(n.) a leisurely walk or journey.
We were enjoying a pleasant bimble over the rocks.

I like the Urban Dictionary’s description even better, don’t you?
“To amble without real aim, yet in a friendly and harmless manner. It’s not required to achieve nothing, though it is a frequent side effect. Bimbling can be made a little more business-like with a slight hunch of the shoulders.”
I rather think Bilbo Baggins enjoyed a good bimble, don’t you? (Now we’re getting into tongue-twisting territory.)
From The First Saint Omnibus: An Anthology of Saintly Adventures (1939), page 269:
