Sailing, sailing over the bounding main...
What is the “bounding main”, anyhow?
The bounding main is where you find it.
A lot of things are bounding as we speak. Not me, though.
“They shuddered to think that the chase might fail, And the Beaver, excited at last, Went bounding along on the tip of its tail, For the daylight was nearly past.” ~The Hunting of the Snark by Lewis Carroll.
