Obviously our naming likes/dislikes are unique to each person (and probably strongly influenced by our primary language/global location), but, in my gaming group of 4 (scattered throughout North America and gaming-enabled through Mumble voice chat and d20Pro virtual tabletop), the following names/words are avoided simply because of how they sound:
Norgorber: I have a player that's avoided making evil stealthy religious builds to this god simply because of how strange this name sounds. Maybe it's the '-gorber' sound?
Rovagug: For a god that I consider to be 'The Big Bad' of Golarion (equaled only, perhaps, in evil street cred/power by Asmodeus, whose name is super awesome sounding, btw), this name sounds underwhelming. Really anything '-gug' fails to convey danger or power (totally IMHO, clearly).
Psychopomp: the '-pomp' sound kills this race's ability for us to take it seriously.
No offense is intended to the individuals responsible for the above listed names; they just aren't my group's cup of tea.
Wow, talk about a YMMV/personal preference discussion!
