That might well be true; my point is that at some point their individual thoughts don't matter, because they're referencing a larger meme.
I'll add that if it were just a funny play on words, we might expect to see a name like "boy" or "guy" or "son" or "person" or any number of other names that are, ha-ha, kind of like "man". The fact that "bro" was picked was pretty obviously a reference to the whole "brogramming" thing.
"man" pages were never really a problem in this vein, because everybody knew that despite the surface similarity (which gave rise to a variety of jokes), "man" was short for "manual", and "fsck" (which also gives rise to some funny jokes) is really short for "file system check" or something like that. "bro" is short for "brogramm(er|ing)". Your attempt to reduce my argument to absurdity in your second paragraph falls completely short because of the total lack of actual parallel to the situation we're really discussing.
