You know, it's interesting you mention that, as, with half a year since the last time I've used "gay" in that sense, and maybe a whopping three or more years before that for the second-to-last time, I actually felt quite self-conscious as I typed it. Different environments evoke different flavors of character and speech, though, and the term seemed more closely aligned with my meaning than anything else. In any case, I'll try to refrain from that usage here just as I seem to have naturally done in the real world (offline, that is).
DISCLAIMER: I don't yet actually drive a BMW. Currently, I proudly drive a '93 Volvo 940, the inspiration for my love of RWD cars.
