The Jargon File (version 4.4.7, 29 Dec 2003):

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 grinders, 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).
