Rubber checks that bounce?

[Rachel Conti]

Oh yeah, I've also heard people being "bounced" from a disco by "bouncers."
It would seem that the term is synonomous with rejected.

OED:
b. trans. To cause to rebound. Also transf., to cause to be reflected.
c. intr. Of a cheque: to be returned to the drawer because there are
insufficient funds to meet it. Occas. trans., to present (such a cheque).
7. To come or go as unceremoniously as a tossed ball, to throw oneself with
excess of physical momentum; to burst unceremoniously into, out of.
