Where does your user name come from?

sounds like subwoofers

Mine is taken from my occupation. I'm a commercial HVAC tech, and subcooling is a thermodynamic term used frequently in my trade. Actually, superheat is the basis for refrigeration, but I couldn't find a way to use it.

No unusually impressive or artificial parts in my anatomy. I am a Biomedical Engineer, hence the tag.

boooooooooooooooooooooooooooooooooooooring I know , mine comes from the first initial of my first name added to my last name. YAAWNNNNNNNNNNN.

I'm a chemist/molecular biologist and in the lab I use pipete aids for liquid transfers. These are made by Gilson and called pipetmans. Sort of a no-brainer to make a moniker out of it, although it's somewhat (hopelessly?) geekish.
Actually, I was quite intrigued to learn, that Subaruguru - one of the regulars here - actually developed these things.
