Airport code for Halifax, NS. I opened a yahoo account >20-years ago using that moniker, that's where I lived at the time. Can't remember why I recycled it for teh, sheer laziness is the most likely explanation.
Edit: OK, that's not the Halifax airport code (it's YHZ). Now I don't remember how I arrived at it, except as a contraction of "Halifax".
