When I was pregnant with my daughter, a colleague tried very hard to convince me to call the baby "Flash". He would ask after "little Flash" and it got to the point, with my pregnancy addled brain, that I could have considered it.
Fortunately, my husband put his foot down and she has a very traditional name that I love.
If I was lobbying for a child-name during the mother's pregnancy, I'd push for "Godot".
My late brother would cheerfully tell anyone who asked if they'd picked out a baby name they were going to call it Throckmorten. Further, he would insist this was true no matter who asked or how often they said no, really, what names are you looking at?
As he told me, that way no matter what they actually did name the baby people would be too relieved to complain.
