Chad Johnson 30 DAYS JAIL FOR SLAPPING Lawyer’s REAR END

UPDATE: The judge did not take too kindly to Johnson’s public show of affection while in a Florida courtroom, so-much-so, your honor threw his butt in jail for 30 days.

Chad Johnson was just kicked out of a Florida courtroom after performing a well-known football maneuver, the ass slap.. The footballer playfully slapped his male lawyer’s ass and the judge tossed in the yellow flag..

UPDATE: Chad and his attorney are back in front of the judge … apologizing … and desperately trying to convince the judge to accept the original terms of the deal.

Johnson was in court in Broward County, FL to face the judge for his recent probation violation in his domestic violence case.

During the hearing, the judge and Chad’s lawyer were about to finalize the terms of Chad’s punishment — terms that were pretty favorable to Chad.

But the whole thing fell apart at the last minute, when the judge asked Chad if he was satisfied with his attorney — and the ex-NFL star reached back and playfully slapped his lawyer’s ass.

Chad smiled … the court erupted with laughter …. but the judge wasn’t amused.

In fact, the judge found the move disrespectful — and lashed out at Johnson … asking him if the whole proceeding was a “joke” to him.

Johnson replied, “I had no intent to make this a joke, because my life is in shambles right now.”

The judge — who lost her patience — suddenly announced that Chad’s deal was OFF … and kicked him out of the courtroom.
