The Game, Problem: Rich Homie Quan Shoulda Known ... Alamo's a Car Rental Joint!!!

The Game and rapper Problem ragged on Rich Homie Quan for screwing up Notorious B.I.G.'s "Get Money" at VH1's "Hip Hip Honors" ... but they don't think it's career suicide.

Game and Problem went on "Raq Rants" Tuesday and showed how it's done ... making it clear it's "Cease and Nino" and not "Cease and Alamo."

And the 2 rappers were jokingly incredulous ... even these West Coast guys nailed it better than RHQ.

Quan profusely apologized, saying he meant no disrespect to Biggie.
