:DPB: /d*-pib'/ [from the PDP-10 instruction set] vt. To plop
   something down in the middle.  Usage: silly.  "DPB
   yourself into that couch there."  The connotation would be that
   the couch is full except for one slot just big enough for you to
   sit in.  DPB means `DePosit Byte', and was the name of a PDP-10
   instruction that inserts some bits into the middle of some other
   bits.  This usage has been kept alive by the Common LISP function
   of the same name.
