'Bouncing' came first. Bouncers are the guys who do the bouncing.
Bouncing as a slang term came from the 1800s or thereabouts.
Considering doing the act of 'Bouncing' would automatically make the person who is doing the act the 'Bouncer', I would say the 'Bouncer' came first as the intention made him the bouncer prior to the bouncing.
