Mine is fairly borning....
Mich is the first 4 letters of my First name Michelle
Low is the first 3 letters of my last name.
Put them together and you have Michlow....
It started way before the forums, I think it was a work sign on many jobs ago.
Most people on the forum actually pronounce it wrong (I assume this, as I don't actually HEAR them). Some say "Mick-low" similar to how Michelob would be pronounced (my nickname from CC1), others say "mish-low" like the Mich in Michelle, this is closer, but not quite accurate.
The true pronunciation is "Meesh-Low", said best like the stuck up maitre'd with a snooty french accent at a fancy restaurant. Why? Because I'm goofy!
My Other user name is My Own Eyes. That was a somewhat snarky play on the scripture that talks about their being no king in Israel, that everyone did what was right in their own eyes. I have a split personality, so have to switch between the two occasionally, or the voices in my head get angry!
