Chad Johnson: Tapping Asses ... It's a Sign of R-E-S-P-E-C-T Chad Johnson Tapping Asses ... Sign of R-E-S-P-E-C-T EXCLUSIVE 6/11/2013 7:05 PM PT

Chad Johnson patted his lawyer's ass in court Monday as a sign of respect ... so claims the tapee, attorney Adam Swickle.

Swickle filed legal docs -- just obtained by TMZ -- in which he pleads with the judge to reconsider her decision to throw out Chad's plea deal and throw him in the slammer for 30 days -- all because she believed the former NFLer disrespected the court with the tap.

In the legal docs, Chad's lawyer says "Mr. Johnson has been a professional football player in the National Football League for eleven (11) years and patting another individual on the backside is viewed as a sign of respect and gratitude."

Swickle also noted that Chad was goaded into finding some form of compliment by the judge herself, who told him to thank his lawyer.
