'decimate'

Damn (sorry, Dagnabbit) I was going to pick that one! And I could have got away with YARTing a bit better, perhaps.
What's striking is that this is a very clear abuse of the original meaning, which was very exact. In fact, so exact as to make the word pretty much useless for modern purposes.

Oh go on then, tsuwm - give us a reference to the original!
As follows:

replacing <with [,>with ] and ??? with appropriate Board name and Post Number.

Yes, OK, I'll get detailed instructions together.... very soon now..
