Documents allege that Michael Jackson used secret code words for sexReuters

Michael Jackson reportedly used secret code words for sex.

Lawyers acting for 36-year-old James Safechuck, who co-starred with the late King of Pop in a Pepsi commercial in the 1980s, have filed court documents asking he be allowed to file a claim against the Thriller hitmaker's estate after being molested nearly 100 times over a four-year period until he hit puberty.

The documents also contain a number of claims against the star.

The documents allege that the accuser regularly shared the singer's bed and revealed that Michael used code words for sex such as calling semen "duck butter" and describing an erection as "bright light, brick city".

According to TMZ, Safechuck also alleged that the singer used secret signals and when they held hands, the Beat It star, who died of acute Propofol intoxication in June 2009, would scratch the inside of his hand with a finger to show he wanted sex.

Other claims in the documents include Michael performing a secret wedding ceremony complete with a ring and marriage certificate with his alleged victim.

Safechuck says the abuse made him question his own sexuality when he developed a crush on the star's then backing singer Sheryl Crow, prompting the Billie Jean hit maker to get jealous and show him a number of unflattering photographs of the All I Wanna Do star.

A lawyer acting for the estate said that all the claims should be dismissed as they have been made so late, and because Safechuck previously stated that nothing happened between the two.

Howard Weitzman said: "Mr. Safechuck's request to file a late claim against the Jackson Estate so he can recover money from Michael's beneficiary will hopefully be rejected."

"This is a person that made his claim five years after Michael died, more than 20 years after the incidents supposedly happened and has given sworn testimony that Michael never did anything inappropriate to him."

The petition will be heard in court on September 4.
