n. 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, card wallopers, and other lower forms of life. This is because (from a hacker's point of view) they 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).
