Add Tyga to the list of hip-hop artists with a “not-so-gangsta” past…

From TMZ

Rapper Tyga enjoyed a cushy upbringing in the Valley — NOT Compton — at least that’s what the rapper said on a game show back in 2008 … and TMZ has obtained the unaired footage.

The show was called “Bustas” — where wannabe-rappers compete against each other to see who can embody ugly rap stereotypes the best … playing borderline-offensive games like “Guess the Rapper By His Grill” and “Is This a Real Rolex?”

Tyga appeared on the show … and immediately sacrificed any semblance of street cred in the process … claiming he grew up in a well-to-do household in the Valley, and his parents drove a Range Rover.

But Tyga — who has since claimed he grew up in Compton — insisted, “I’m still street.”

Thankfully for Tyga, the show was never picked up and the clip never made it to air … until now.

The highlight: “Bustas” culminates with a freestyle rap, in which the contestants are asked to incorporate buzz words like “amoeba” into their raps, and Tyga’s so bad … he gets his ass boo’d off stage. (For the record, Tyga does not know how to pronounce the word “amoeba”)

It’s pretty bad — but you should check out the video to see if Tyga actually loses the entire show.
