ere is one for you etymologists.  The Babcock Foundation reported in a recent E-mail, that the orgin of the term picnic, orginates from the act of taking a male slave and killing him during a family/community celebration.  I did not make this up. . .   If any of you out there could find the true orgin I would like to know!  The best I found is that it is German (Picknick) or French (Pique-Nique) and dates to 1748.
