“You better walk that way. You better walk that way you fa***t motherf****r. You gotta come to Denver bi**h.”

- Kenyon Martin to Dallas Mavericks owner Mark Cuban after the conclusion of Game 4 on Monday night.

Upset much, Kenyon?

Dallas Mavericks owner Mark Cuban might have finally crossed the line.

Normally, it’s pretty easy to ignore his postgame antics and cheap shots at referees, but Cuban’s latest assault was towards the mother of Kenyon Martin.

Cuban allegedly confronted Martin’s mother, Lydia Moore, and according to Kenyon’s agent said “Your son is a punk,” following a frantic Game 3 ending which saw Dallas lose 106-105.

Cuban also used the term “thugs” to describe the players on the Denver Nuggets and the NBA is reviewing the situation.

Real classy, Mark.

And don’t expect Kenyon to back down.

He wants to talk to Cuban, face-to-face.

“(Heck) yeah, don’t say nothing to my kids or my family,” Martin said. “If you got something to say, say it to me. But I’m going to take care of it. I’m not going to do the whole media thing, back and forth. That’s his thing. I’m more of a face-to-face type of dude.”

Sadly, this is the only excitement in the Dallas-Denver series so far.
