pop: /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 or PDL. 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.
