The act of
inconspicuously exiting a popular social scene, usually a dance floor, with intentions to receive oral sex, AKA heenan, or partake in
sexual intercourse. In order to slide off, one must successfully engage in stimulating
conversation but quickly disperse from the rest of the crew without others wondering your whereabouts. Only upon returning post-nut bust is a slide off successful. Otherwise, you just dipped out with a girl.
