Horizontal Shuffle 

Noun; the act of engaging in sexual intercourse, which is usually associated with two people laying on top of each other on a horizontal surface and engaging in rythmic sex screwing, which may or may not bear resemblance to a dance.

I asked my girlfriend if she would like to do the Horizontal Shuffle, she obliged and so I laid some serious pipe on that broad. I felt like Super Mario after I was done with her.
