In honor of giant douches like Rick Warren, someone decided to coin a new word: saddlebacking.
Saddlebacking: sad•dle•back•ing \ˈsa-dəl-ˈba-kiŋ\ vb [fr. Saddleback Church] (2009): the phenomenon of Christian teens engaging in unprotected anal sex in order to preserve their virginities
After attending the Purity Ball, Heather and Bill saddlebacked all night because she’s saving herself for marriage. Unfortunately her parents found out because they got santorum all over the sheets.
