There's actually some names listed on here that I really like Luna, Lincoln and Wren! Different strokes for different folks, I guess.
Without meaning to sound peak Mumsnet, my pet hates for names are anything obviously chavvy sounding, with a particular dislike for deliberately quirky spellings or hyphenated ones with unusual spellings ("Ellie-Mei" etc). There's then some which aren't obviously chavvy but are just plain bad in my opinion, like Sonny (apologies to any parents with a Sonny on here. But you wouldn't call a girl Daughtery would you, lets be honest).
I also cringe at the name Bear. Mostly because I suspect it was started off by fans of Bear Grylls, whose real name isn't even Bear! It's Edward.
People calling their kids Khaleesi when the character isn't even called Khaleesi is another one.
