Oh, for crying out loud:

Former Pennsylvania Senator Rick Santorum is ardently anti-gay and has an acute talent for tapping into the homophobic imagination of social conservatives. “Man on child,” “man on dog,” incest, “priests with 3-year-olds,” polygamy, the welfare of children, the decline of Western civilization—if it’s in the vocabulary of anti-gay hysteria, Santorum has been there, done that. As a result, he’s become the target of a Google bomb, led by gay columnist Dan Savage, that successfully redefined “santorum” as a substance most straight people probably didn’t know existed and most gay men never thought to name, especially not in honor of a Republican US Senator. But hey, shi* happens—and now Santorum is widely considered a joke. The launch of his presidential campaign today was greeted with a chorus of knowing sneers.

There are a lot of straight people out there having anal sex. Not most, but approaching most:

In 1992, 16 percent of women aged 18-24 said they'd tried anal sex. Now 20 percent of women aged 18-19 say they've done it, and by ages 20-24, the number is 40 percent. In 1992, the highest percentage of women in any age group who admitted to anal sex was 33. In 2002, it was 35. Now it's 46.

And considering that straight people outnumber gay men by a factor of 10, 20, or 40, depending whose estimates you believe, most of the buttfucking that goes on out there is straight buttfucking. So santorum is something that lots of straight people are familiar with. Intimately familiar.

And remember, kids: If you're doing anal right, there's no santorum.
