Tekashi 6ix9ine can never use the phrase "TREYWAY" again - or he'll be sent to prison. Yesterday the rapper was spared jail time, as a NY judge decided to give the rapper 4 years of probation, instead of 1 to 3 years in prison.

The prosecutors pushed for prison time for Tekashi - but the judge spared him . . . sort of.

You see, the stipulation of Tekashi's probation are stringent, and also bizarre.

The 22 year old rapper is warned to stay away from trouble, and to not associate himself with active gang members. That's pretty normal.

But he judge also told the rapper that he is not to use the word or words "TreyWay" in his music or on social media. According to the terms of his probation, if Tekashi utters the words Treyway - either on social media or in his rap music - he's going to go to prison.

The 22-year-old rapper from Brooklyn, New York pleaded guilty after online videos surfaced of him sexually engaging with an underage girl in Oct. 2015.

Hernandez was seen sexually touching the child, including standing behind the child in the video while “making a thrusting motion with his pelvis and smacking her on the buttocks,” according to a complaint filed with the criminal court of NY.

At the time of the incident, Hernandez was 18-years-old. The victim was 13.

“The defendant, knowing the character and content thereof, employed, authorized and induced a child less than seventeen years of age to engage in a sexual performance, and being a parent, legal guardian and custodian of such child, the defendant consented to the participation of such child in a sexual performance,” court documents stated.
