The disabled teen 50 Cent mocked as "high, stupid" at the airport speaks out

50 Cent has been heavily criticised online after mocking a teenage janitor were a severe social anxiety disorder - and accusing him of being HIGH.

In a video shared on Instagram - which has since been deleted - the rapper can be seen and heard insulting the man as he was pushing a cart of cleaning supplies through Cincinnati/Northern Kentucky International Airport.

As the youngster ignores the star, Fiddy can be heard saying: "The new generation is crazy. They're crazy. What's your name?

"Look at him. What kind of s*** do you think he took before he got to work today? He high as a motherf****r right here in the airport. Pupils dilated - the new generation is f***ing crazy."

However, the rapper was slammed online for his comments, with an Instagram user quickly identifying the man as Andrew Farrell, 19, who recently graduated from Cooper High School.

The user wrote: "I went to school with him... He has extreme social difficulties just to let you know.

"He has a hard enough time getting through life without jackasses like you making fun of him. I hope you feel good about yourself. You just lost a huge fan."

Meanwhile, Farrell's mother and stepfather Amanda and Ken Framer have spoken out to defend the young man.
