Kanye West has been criticised for using the word spaz during his rap on Four Five Seconds, which sees him collaborate with Rihanna and Sir Paul McCartney.
The lyric is: “Then I heard you was talkin’ trash, hold be back I’m ‘bout to spaz”.
Chief executive of charity Scope, Richard Hawkes, told the Sun: “Many disabled people find the word ‘spaz’ very offensive.
“Kanye West is a huge star, listened to by millions of young people who might be influenced by his songs.
“It would be such a shame if the word became commonplace again.”
The charity have reached out to the father-of-one and asked him not to use the word again in his lyrics.
Kanye, Rihanna and Sir Paul are expected to perform the track at the upcoming Grammy Awards.
However it is unclear at this stage whether he will still include the offensive word.
It’s not the first time Kanye has managed to offended those living with a disability.
In September of last year he stopped a concert in Sydney because not everyone was on their feet.
However, while he refused to carry on until everyone stood, he was unaware that one of those not standing was in a wheelchair and the other had a prosthetic limb.
