"Rose-lipped maidens, light foot lads"

"Rose-lipped maidens, light foot lads" was a toast in the film "Out of Africa". What does it mean? Where does it come from?

It's from A. E. Housman's Shropshire Lad:

With rue my heart is laden
For golden friends I had,
For many a rose-lipt maiden
And many a lightfoot lad.

By brooks too broad for leaping
The lightfoot boys are laid;
The rose-lipt girls are sleeping
In fields where roses fade.

At one point in my life, I made a habit of memorizing poems, particularly when spending time in airplanes. I nearly wore out my copy of Shropshire Lad, and had at least 15 poems from that wonderful book memorized. Many of those memories have faded like the roses....
