I used "whacked" has a double entendre. The first meaning was in the Whitney Houston-Diane Sawyer-interview sense or something being "out of whack". The second meaning, when I said "de-whacked", was a reference to "whack" as a synonym for "slash". IOW, the URL was "whacked" because it was missing a "whack".
BTW, LOL @ Bob's indignation at being nitpicked about the error.
