While
having sex, you drink a nice,
refreshing bottle of Arrowhead water. After it's empty, you take a big 'ol shit in it, then shove it up your partner's orifice and give it a squeezy-squeeze, thus emptying the fecal matter into the body of your partner.
note:nearly
impossible to clean.(EXTREME DOUCHING REQUIRED)
Dorothy said to me last night, "I got me a MEAN 'OL arrowhead
chocolate extravaganza last night! I couldn't clean
that shit out, it's still in there!"
