3:00 PM PT -- Tyga says the song is almost 2 years old. He was still with Blac Chyna back then, so he seems to be saying "Pleazer" has nothing to do with Kylie.
Tyga just released a sultry, romantic song about his GF Kylie Jenner -- nah, just kidding ... he's actually dropping a rap about illegal sex ... y'know, like with a 17-year-old.
Tyga does not shy away from the obviously sensitive issue with his new song, "Pleazer" ... 'cause the 25-year-old included these lyrics:
I hit her, she backwards, lickin' her a**holeMy d**k is the passwordT nasty, 'bout to catch a felony for itVagina juice like orange juice in the mornin'
We know it's show biz, but ya gotta wonder -- is Kris Jenner still okay with this guy dating her underage daughter?
