A sex term, is put into play when a girl sits/shoves a soda can in her colon or vagina, the male then proceeds to punch her in the stomach causing the can to fire out of her rectum. This resembles a soda machine.
A sex move when someone pisses in the girls vagina during sex, then she bitches about it and he sucks the piss out of her anus. He then procedes to spit it on her face and run away.
When a girl falls off of a wall onto a guy's member, much like how a soda falls from its stock to the recieving bay in a soda machine. Results have not proven successful (men, you may be hospitalized).
The first time I saw her, I wanted to give her The Soda Machine. Then I found that was stupid because now im sitting in a hospital bed with a dick split in two...
Flip a girl upside down, open her pussy lips, pour a drink of your choice into her vagina, let it settle, and flip her right side out and suck out that succulent juice of yours.
Rob: Hey kyle did you do anything with Emily last night?
Kyle: Yeah, I gave her a Mississippi Soda Machine
