I have been Jeff Da Weasel for many years.
It all started when I wrote an article for a music/audio magazine once, in the late '90s. I was sick of all the bullshit little author bios that you see at the end of an article. Most of them say something like, "Bill Williams is a noted expert on tree bark, and lives with his wife and three sons in the Pacific Northwest," or something similar.
So, for my bio on this article, I had them put (with names redacted), "In addition to being a lifelong musician and engineer, Jeff Xxxxxxx is the king marketing weasel of Xxxx Corporation."
And it stuck. I figured that since eveyone else called people in my profession "marketing weasels", I might as well go with it instead of fighting it.
Bird in a flying cage you'll never get to know me well.
