Okay, I get "technical writing." In fact, I've even been a technical writer (sung to the tune of Paperback Writer - 'cuz I wanna be a technical writer... TECH-NIC-KUL WRITER!!!), but I've never heard of a technical dancer.
Or a technical dance, for that matter. Is that like taking interpretive dance to a new level, where, upon viewing the dance, you'll be able to fix your television? Or use MS Word?
Or is it more like a description of me on the dance floor, as in, "I mean he was moving and all, and there was music playing and stuff, so, yeah, I guess he was dancing, technically,.."
