Michael Jackson allegedly had sex with children, this we know. Logically, it follows that Jackson would have had to communicate about sex to his alleged victims in a way that was more, uh, compatible to a developing mind. Thus, the very weird code names he is said to have had to describe his semen and erections.

This all comes from a lawsuit filed by a man named James Safechuck, who says Jackson abused him as a child during a period in the late '80s when they were known to have spent time together. TMZ has gotten a look at new court documents regarding an ongoing lawsuit by Safechuck against Jackson's estate, which bring the following claims. Apologies in advance:

In new court docs — obtained by TMZ — Safechuck says Michael taught him to use code words ... referring to his erection as "bright light, brick city" ... and calling semen, "duck butter."

Safechuck claims Jackson also used secret signals — when they would hold hands, Michael would scratch the inside of James' hand with a finger ... to show he wanted to have sex.

Jackson's nearly unmatched genius as a songwriter apparently did not carry over to euphemisms for jizz.

In addition to those allegations, Safechuck says that Jackson would give him alcohol and show him porn (a recurring detail in claims against the singer) and that he even performed some sort of marriage between the two that involved a ring and certificate.

Jackson, obviously, isn't around to refute these claims to either the public or a legion of attorneys. TMZ talked to his estate's lawyer who says that the suit should be dismissed because "it was filed more than 20 years after the incidents supposedly happened." He also says that Safechuck has given previous statements saying that Jackson never abused him.

Jackson's musical legacy was revived this year, but it doesn't appear as if his other, more sordid one will be going away either.
