Yes, I've heard the "make me a sandwich" jokes already.
I worked the lunch shift and I had this regular customer who came in a few times a week to get a hummus pita. If you don't know what hummus is, it is a delicious and flavorful spread made of mashed chickpeas and spices. It's often served with pita bread as an appetizer, or as a side or dip for various Middle Eastern or Greek dishes.
Anyway, after a few weeks of making the same pita for this woman, she told me "you know, you make the best hummus pita here." I smiled at the compliment and responded, "Well, I just make yours the way I would make my own. I really like hummus IRL." As the last letter of the acronym escaped my mouth, it twisted into an awkward tone as I realized the error in my sentence. Immediately flustered, I stuttered, "Err-- I mean... I like hummus... Uh..." She laughed at me with a smile and replied, "Don't worry, I know what you meant." But my nerdiness was already exposed; I was prone. I sensed an incoming AoO. It never came.
At the time I was probably overreacting, granted. The usage of net speak is pretty acceptable and easily understood to the average person these days. "BRB" doesn't bewilder most people, for example. On the other hand, I find myself telling my friends once a month, "I don't feel like going out: girl debuff," always getting mixed responses.
Recently, a friend of mine going off to college soon came to me for some advice on dorm living. I told him, "if you want more privacy, just bunk the beds." Before I could continue, he followed up with "oh yeah, that'd block LoS." I stared at him, dumbfounded. Had someone just out-nerded me?
So what WoW terminology do you use in your everyday life? How do your friends who don't play WoW react?
