It's pervasive in everything, even in the names of stuff. E.g. there's a recent programming language that calls its interpolated strings "G-Strings". That's the class name in the code. A method for finding out the length of the "G-String" was added, called "size", in addition to the existing one called "length". So...
assert "----V----".size() == 9
The language designers who invented those names had a good old laugh at the pun in the mailing lists. But female programmers are often offended, and have a case for having that language (and related web framework) banned from their workplace, in favor of another.
We often say in the Perl world that objects that are ported to Moose "grow antlers." Arguably this is at least as female-hostile statement since only male moose grow antlers and therefore it establishes a male-normal perspective.
