What does it mean if a man says, “you seem cool, we should meet up”?

[Anonymous]

I mean the “cool” part

[sheikalana]

It could mean several things like funny/easy going/friendly/nice. It's a positive thing.

Just that you seem like a fun and interesting person to be around.

You seem interesting, and fun.
