No, actually, it's a derivative of my last name. It's a nickname that seemed to pop up at any school I went to, job I got until after school, etc. We even had a Pac-Man game in the student lounge of the law school I attended. I groaned when I saw that in the lounge...then decided to finally quit fighting it.
Now, toss me a pretzel, and let me at the blue ghosts!
BTW, grandkids...as an uncle four times over, I know why my parents smile...they spoil their grandkids, and when the little varmints act up, it's someone else's problem. I get it.
