flowchart
n.
[techspeak] An archaic form of visual control-flow specification
employing arrows and speech balloons of various shapes. Hackers never
use flowcharts, consider them extremely silly, and associate them with
{COBOL} programmers, {code grinder}s, and other lower forms of life.
This attitude follows from the observations that flowcharts (at least
from a hacker's point of view) are no easier to read than code, are
less precise, and tend to fall out of sync with the code (so that they
either obfuscate it rather than explaining it, or require extra
maintenance effort that doesn't improve the code).
