Jetsam, noun, unwanted material or goods that have been thrown overboard from a ship and washed ashore, especially material that has been discarded to lighten the vessel.
Flotsam and jetsam, floating wreckage and unwanted goods thrown off the vessel of modern life. There's a lot of it about, in no particular order:
Harvard, Satan's Vatican
Madonna, Queen of Pop
Justsin Welby, titular head of WANC (Worldwide Anglican Non-Communion)
The sheer genius of Yoko
And liturgical dance, which is so very loved by all
Don't get me wrong, this isn't an exhaustive list, just a snapshot. Feel free to chime in.
Cheers,
