What occasions would call for bringing up your geek girl lingo in the workplace? As long as you stick to your work, I doubt that most topics would come up.
I too am a geekette with a rhetoric that make most people blink, but I've found that there are things beyond this personality that affect workplace relationships. Once I realized this, life became soooooooooo much better.
The best thing in pretty much any work environment is to not feel like you have to fit in. You are there to work, not to make friends. YOU DON'T HAVE TO LIKE EVERYONE OR BE LIKED! Professional relationships and common courtesy are necessary, but being buddy-buddy opens up a whole new can of worms. Work is a whole separate world from other aspects of your social life. What may be best for work may destroy a friendship because too many people can't separate the two. Imagine that you're the manager of a branch, and that you have to downsize. Imagine that one of the weakest links is a friend of yours. Would you feel like a bad person, and would s/he feel betrayed, even though the firing has nothing to do with the friendship? Would you let friendship get in the way of what would be best for the company? I'm asking this to give a perspective of what's really important in the workplace.
While I don't totally bar out friendships with coworkers, I find it best to be on more of a professional, slightly distant relationship with them. In other words, don't mix work and personal life. If you get buddy-buddy, there will be feelings of betrayal and other actions that result from actions that are best for the workplace. I'm not saying this always happens, but I've found that many people who go in trying to be popular and friendly and harmonious with everyone usually end up disappointed.
This is an excellent article
on social expectations and realities in the workplace, and different ways to avoid pooping where eating. Seriously, don't worry about being popular or liked. Keep the goals in mind, and don't let petty grudges, cliques, or popularity contests discourage you. Seriously, read it. It will tell you everything you need to know.
Although this is a touchy subject, I will also mention gender differences. Men are taught to be competitive, so they are socialized to separate work and personal. If you ask a male friend an opinion about how you are doing in your job or something similar, he will usually tell you. If you ask a female friend the same, she will all too often sugar-coat the truth or say something along the lines of, "I'm afraid that my opinion would hurt our friendship." This is because women are taught to be social, and that thay have to be liked by people that they have no choice but to be around. Don't fall into that trap, whether you are male or female.
