hummer has been my nickname for a long, long time. Before the Internet (well, not before the invention of the Internet, but before the prevalence of the Internet). Before the SUV (not before the M998 Humvee, but before the Hummer).
When I was a wee little gaffer, I played hockey, like any good Canadian did. One time, when I was about 12 or 13, I used the phrase "I'd like a hummer from her" to refer to a certain sexual act. None of the other kids on the team had heard said word in that context before. I had to explain what I meant. And thus a nickname that spanned a decade of hockey was born.
Just like rayden54, the 010 comes from hotmail in the late 90's.
