during rear-entry coitus (doggy-style)--most typically unprotected intercourse where the receiving party (the "catcher") has either inferred or implicitly stated that the "preacher" refrains from filling him/her with their "holy water", the person doing the penetration, upon reaching an orgasm shouts:

"SHAZAM! YOU'VE-UH BEEN-UH HEALED MY CHILD!"

note: emphasis should be placed on the usage of a southern accent and a quick (but hard) push onto the head of the "church goer" upon yelling "Shazam!"

variants include: "going televaginalist" , "pulling a preacher", "going preacher" or "baptist"
