A variable in a programming language that was supposed mean that a certain match was ok. But because no camelcasing was used (like matchOk), it became a not understandable non-sense variable.
boolean matchok; // FIXME what??
Programmer 1: what does matchok do?
Programmer 2: matchok?
Programmer 1: yeah matchok.
Programmer 2: it checks if you have matchok.
Programmer 1: whatever
