Anus Geyser

When someone’s anus is open wide enough to fit mentos inside, some tosses in a few mentos and then pours in coke into the hole, thus causing a massive explosion straight out of the anus

“Mark what are those mentos for, I thought we were going to have sex”, “open up Susan, the anus geyser comes first”.
