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.
Person 1) Did you see Jackie Chan chairing in that scene?
Pereon 2)
Nah, I was
fingering your
sister.
Example 2)
Lady 1) how was sex last night?
Lady 2) Terrible, i started chairing him just so he would finish
