pop

   [from  the  operation  that  removes the top of a stack, and the fact
   that procedure return addresses are usually saved on the stack] (also
   capitalized `POP')

   1.  vt.  To  remove something from a {stack}. If a person says he/she
   has  popped  something  from his stack, that means he/she has finally
   finished  working on it and can now remove it from the list of things
   hanging overhead.

   2.  When a discussion gets to a level of detail so deep that the main
   point  of  the  discussion  is being lost, someone will shout "Pop!",
   meaning  "Get  back  up  to  a higher level!" The shout is frequently
   accompanied by an upthrust arm with a finger pointing to the ceiling.

   3.  [all-caps,  as  `POP'] Point of Presence, a bank of dial-in lines
   allowing  customers  to  make  (local)  calls  into  an  ISP. This is
   borderline techspeak.
