1) The act of being in the seated position as if seated in a chair only without an actual chair. Usually an
impossible kung fu maneuver seen in movies by expert martial artists.
2) The act when a girl is riding a guy top side, then shifts her feet forward and bounces as if
getting up and down from a chair repeatedly. Typically, this speeds up the climax time for the guy, leading to less
satisfaction by the female, unless the sex is horrible and she just wants it to end, then she can chair the guy and that would mean she is chairing him.
