We hope Rich Homie Quan likes his lawsuits shaken and not stirred ... the security guard he allegedly beat unconscious in Miami is now dragging him to court.
According to docs ... Christian Cajigas says he's been disfigured and left in intense physical pain and is suing for the attack that he says left him beaten to a bloody pulp outside LIV Nightclub in Miami Beach.
As TMZ previously reported ... last Saturday RHQ and his boys were allegedly turned away by Cajigas at the club, and that didn't sit well with James Quan-d who allegedly wailed on him before taking off on a speedboat like James Bond.
Cajigas and his attorney Eric Hertz -- the same guy who represented the woman Tim McGraw slapped -- are asking for an unspecified amount of cash ... but it definitely sounds like a lot.
That boat ride could end up pricey.
