Should I rename my hamster again?

I've had my hamster for about 6 months and I've changed his name like...twice. But I never seem to like his names! right now his name is Pretzel. But I never even like to call him that. I feel bad that I keep changing his name but, he doesn't know! Oh and everyone is like "why do u keep changing your hamsters name?' and i don't know but it makes me feel embarrassed. I really want to rename him Nico because well I don't really like the idea of naming a pet after a snack food...So I'm asking, should I keep his name or change it to Nico? Please help(:
