he means that if ward tries to cheat green is gonna deal with it better. no point being mr nice guy like kessler. when dirrell cheating against froch with the constant slipping and clinching froch started the rabbit punches. that is how fighters work - you cheat they cheat.
I hope that by "language" he means; "When Ward head butts me I'm gonna slam a knee in his nuts, and an elbow in his eye socket." I'm still amazed that Kessler took that **** without retaliating. I'm also very curious about why Adamek and Arreola had zero problems with Jack Reiss, but Ward/Kessler made him look like the worst ref in recent memory.
