Old Slat = real board ?  :D

OS, I kind of liked the sound of it, so I went with it, too.  Here's what the dictionary has to say:
****

noun
1.
a long thin, narrow strip of wood, metal, etc., used as a support for a bed, as one of the horizontal laths of a Venetian blind, etc.
2.
Aeronautics. a control surface along the leading edge of a wing that can be extended forward to create a gap (slot) to improve airflow.
3.
slats, Slang.
the ribs.
the buttocks.
(initial capital letter) a nickname for a tall, slender man.

I'm thinking "Old Slat" is preferable to "Old Buttocks"... but that's just MY opinion.
