What is The Slide?
1.
This is a casual dance move, performed while your attention is focused on something completely different (ie. out a window). The hands move casually backwards and forwards, one above the other without touching and creating a simple yet extemely effective and easy-to-use dance move.
Duuuude, she's doing The Slide...

2.
A sexual act in which the penis never enters the vagina, just slides in between the two vaginal lips. It looks like a hot dog sliding in a bun.
I get an orgasm every time I do the slide!
