For the uninitiated, “xXx” is the code name for Xander Cage, Vin Diesel’s protagonist. It also has the added bonus of implying the movie you are about to see will be EXTREME. TOO HOT FOR TV. Etc.
An unfortunate side effect is, pretty obviously, it’s hard to Google this movie without, y’know, finding a bunch of porn. To that end, let’s look at how the xXx series’ SEO stacks up against the internet’s ultimate sweetheart: full-on sex.
Short version: Don’t title your movie or project xXx. (via Craig)
