The 25-year-old "Rack City" rapper recently dropped his latest song "Stimulated" with the lyrics saying, "They say she young/I shoulda waited/She a big girl, dawg/When she stimulated."

Upon its release, many speculated that Blac Chyna's ex Tyga is singing about sleeping with Kylie Jenner eventhough she's still very young. The "Keeping Up with the Kardashians" star just turned 18 early this month.

This also prompted a number of Twitter users to bash the rapper for releasing the "disgusting" and "sick" song, E! Online said in their report.

"Stimulated by Tyga is probably the most disgusting song I've ever heard," one Twitter user said.

It can be recalled that after Blac Chyna and Tyga's split, the rapper started dating young reality star Kylie Jenner. The then unconfirmed relationship has gathered numerous criticisms, most of which is against the "Rack City" singer.

Meanwhile, the rapper is rumored to be going broke as he maintains the luxurious life of the "Keeping up with the Kardashians" star. Allegedly, Kylie Jenner is used to others spending money for her.

Recently, Tyga has gifted Kylie Jenner with a white Ferrari for her birthday, apart from the expensive clothes, bags and other things that he has offered to the reality star.

A source from The Hollywood Life said, "Kylie is spoiled and used to getting what she wants."

The insider added, "Kylie could definitely buy herself almost anything she wants but she doesn't like to spend her own money. She's used to people buying her things. Now that her parents aren't doing it anymore it's up to Tyga."

And previous reports said that Blac Chyna thinks Tyga cannot afford to pay the car he has gifted Kylie Jenner as he cannot even pay his own rent. The rapper has recently been involved in a case against his landlord after he failed to pay his rent for a couple of months.
