During this act each participant lines up according to penis size and voraciously jackhammers the male with the tightest cornhole ("receiver") until they ejaculate, one at a time filling the colon with an emulsion of personal lubricant and fecal matter ("Santorum").
Next, the second most hung male penetrates the colon extremely deeply and performs the most aggressive form of anal intercourse done at such a speed/force that the anus loses all tightness and what was once a happy starfish is now a hot red pit ("code red anal").
Simultaneously, while the receiver is fluffing the most hung male and getting absolutely throttled in the ass, the most hung male grabs the back of the receiver's head and forces the receiver to deep throat beyond his capability.
The violent gag that results sets off a chain reaction that begins with a sphincter clench. The combination of this clench with a well-timed inward thrust from the #2 douche rocket creates a massive high-pressure colon-bubble that explodes at a high velocity from the receivers gaping colon, covering the #2 douche rocket in a mixed batch of steamy Santorum.
"Mitt really timed that one nicely, Newt didn't even see that Santorum Surge coming."
"Fuck a glitter bomb, that toxic Santorum Surge just blinded Newt."
"Wow, that guy just blew up. What a well executed Santorum Surge!"
"Oh shit, somebody throw Mitt a couple bate-mates, he has one hell of a mess to clean up after that Santorum Surge!"
