What does it mean?

Gees is just an interjection that expresses surprise, or sometimes frustration. You might see it sometimes spelled as geez. It’s a pretty harmless expression to say, i.e. you could say this in casual office conversation without shocking anyone. It’s based on the profanity “Jesus!” or “Jesus Christ!” which are also used to express surprise or frustration. Both of those would be considered more profane, yet still fairly harmless.
