Rough night for Drake, who got booed off stage at his pal Tyler the Creator's music festival ... due to a crowd that clearly wanted, and expected, to see someone else. Also, Trina's shopping trip to Walmart turned racial when another customer allegedly called her a "n***** bitch" ... and cops ended up getting involved.
