Vinny Guadagnino has apologised for his insensitive rap about a woman being raped.
The Jersey Shore star uploaded a video of himself performing the number entitled Rack City Mix which had explicit and offensive lyrics.
His explanation of the track was that he "felt like being a naughty boy and rapping like a G".
But sexual assault organisation, the Rape, Abuse and Incest National Network (RAINN) and his Twitter fans soon showed their disdain for the song and the harmful words.
The song inlucded the lines, "I've got a date for ya, and it's in my pants," and, "I like your crack girl, I wanna take a hit" among others.
Initially Guadagnino was defensive and did not appear to understand the magnitude of his actions.
"Whoa! Some people really know how to take things out of context! #LearnToListenToMusic It was fun though! (sic)'' the reality star tweeted.
But later Guadagnino was decidedly more contrite.
"Sorry for offensive rap," he wrote.
"I'm 100 per cent against violence & work with many organisations to stop it. Will continue to do so."
A RAINN spokesperson told TMZ that Guadagnino's rap song was irresponsible.
"Trivialising this violent crime sends a dangerous message to the public," the representative said.
"Use of the term 'actin' like' doesn't mitigate the harm this crime has on survivors of sexual violence.
The 24-year-old has now taken the video down from YouTube and said it was mean to be a "funny take on an already dirty song" since he is normally known as a "good boy".
