> On the topic of foobar - CS has pretty much wholly converted the usage away from FUBAR - "foo" and "bar" are now commonly used variable names that have a colorful history but aren't frequently associated with errors - they're more commonly associated with anonymous variables.

That wasn't really the point I was trying to make. I don't think that it is problematic that foobar implies "fucked up beyond recognition". That is not an offensive phrase. It's a little uncouth, but not offensive on its own.

And penetration is not an offensive concept! It's what we call one thing going into another thing. Sex also involves this, I am told. Even killing isn't inherently offensive. We kill germs and mosquitoes (and mysqld) frequently and intentionally.

What really needs to happen is the accurate placement of blame. Like you say, the penetration jokes need to die (for the same reason the Uranus jokes needed to die in 2620). The penetration jokes directed at applicants by recruiters really need to die. But the use of the word "penetration" in security is not at fault, it's just an accurate term.
