Parent speak for one of the following definitions:
1)You know, I really don't like your boyfriend at all... but I don't want you to get mad at me.

2)Why aren't you dating that boy? I know you don't like him at all, but I really think that you should date him.
Example 1: When Dani brought home her boyfriend who went by the name "T-Jizzle", all her mother could say was "He's a nice boy..."

Example 2: After Richie, the president of the chess club and algebra team, asked Dani for a date and she declined, all her mother could say was, "Oh Dani. He's such a nice boy!"

He acts like a good guy, and perhaps deep down he is. He believes he is upfront and to the point, while also simultaneously playing games with sex being his primary motivation. He’s all about his friends and the girl he is talking to or hooking up with comes last.

When he’s with you, he acts like a genuinely nice guy and wants your company. But when you part ways, that’s it for him.
Mark is such a nice fuck boy. Run now!
