Chris Brown put the charms on a parking officer yesterday in L.A. -- successfully dodging an expensive ticket -- but in the process ... he hurled another NASTY homophobic slur.

Before sweet-talking the cop, Brown accused several cameramen of alerting parking enforcement officers that his car was illegally parked, ranting, "Y'all n**gas is weak. Did you all call them to try and film me? Y'ALL N**GAS IS GAY."

It's not the first time Brown publicly disparaged gay people.

Back in December, the singer got into a Twitter feud with ex-B2K member Raz B ... calling Raz a "homo" and a "d**k in da booty ass lil boy."

Smells like another insincere apology is in the wind.
