Tyga's stuck in a really bad contract ... with the devil ... according to 2 women who fought through his security guards in Hollywood to give him a loud and bizarre warning.
The scene went down outside Argyle nightclub -- Tyga was pimpin' in his red Ferrari without a care in the world -- when the women bum-rushed him and started going off about his dealings with the devil. Watch ... Tyga and his entourage are perplexed, and then the ranting chicks claim it has something to do with his son, King.
It's strange, for sure ... and the Tyga fans/haters had some words for Kylie Jenner and Blac Chyna too.
One big hint: They make it sound like it's got something to do with money and an ex.
Not shocking for Tyga, lately ... who was also mum about his alleged $200k tab with a jeweler.
