What does guys really mean when they say.. "she's cool"

[Anonymous]

I would always overhear this guy I'm seeing, talking to his friends saying."oh she's cool. she straight, she don't trip."

I'm not really sure what this means.whether it's a really good thing for me, or it just really means that he just finds me cool, and that's it. When guys say this, is it something you find great about a girl or something that is just most commonly used to describe a girl when asked by friends? I'm really curious.

to be honest with you, when I say that it means I don't want to be mean and just straight out say, she is not attractive. To a guy cool is someone you can chill with like a guy, cool doesn't give me a boner, I know that. well that's just me, other guys could be different.

Good question, I would like to know this too! I think maybe he doesn't want to elaborate and spill all your business, but that's just my opinion
