Tyga -- "Where All the Little/Loyal Girls At?"

Tyga dodged a bullet, some say, now that Kylie Jenner is 18 ... but he may have resurrected the criticism that dogged him for a year by asking the crowd Friday night, "Where all the little girls at?"

Tyga performed at First Slice Media Party .. the world's largest pizza festival hosted by DJ Steve Aoki and gave the shout-out right before performing "Loyal" at the Bev Hills mansion.

To some, it sounds like the rapper says "little" and others hear "loyal." Either way ... we're not too sure.
