What does it mean if you invite a coworker to a holiday party ( well something like that )?

you kind of joke around with them somewhat flirtatiously, every once in a while- they tell you ( after you made an off the wall wisecrack comment to them - they say , only business. NO time for good clean fun. Other coworkers i invited also. Kind of a stupid question, but what do you all think?

Sounds like you enjoy your co workers company and would like to extend the relationship to do more fun activities outside the work place.
