Mini-van... sticking two fingers in a girls vagina and five fingers in her anus, simulating the seating capacity of a minivan. Two in the front, five in the rear.
mini van is when a person gives a female two fingers in the front and five in the back. Just like a mini van, two seats up front and five in the back.
I went to a party last night and this girl wanted me to finger her. I asked her if she would want a mini van. She didn't know what it was so I gave her one. She seemed ready for the two up front, but the five in the back caught her off gaurd. She must be used to only corvettes.
you, "hey i think that molly wants to go out with me!"
me, "well, good luck pulling up to her house in your mini van - why don't you save yourself time and humiliation and just go watch some more anime and jerk off."
