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.
