7:55 AM PT -- Chad was arrested in the courtroom and has been ordered to serve 30 days in jail. 7:45 AM PT -- 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.
Chad Johnson was just kicked out of a Florida courtroom ... after the former NFL star playfully slapped his male lawyer's ass -- a move that ENRAGED the judge, TMZ has learned.
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.
