Exactly. I'm no fan of Mark Cuban's...but the allegation would have to imply not only that, but that her jeans were very loose.
I have not read the police report or really know the details, but as others have already commented, this scenario doesn't make sense if this woman really didn't want Cuban to grope her. Otherwise, it looks like she went along and had regrets afterwards.
It would be almost impossible for any man to force his hand down the backside of a woman in jeans and manage to do what this woman says Cuban did, without a little cooperation or assistance on her part.
It's apparently a he-said, she-said but Cuban probably did something to warrant the complaint.
