All surnames and (to a lesser extent) place names used as first names
All nicknames instead of real names
Names that are or sound made up: Jayden, Kai, Lacey etc.
Names which are not intrinsically terrible but have become chavvy, like Liam
'Sensible' yet super-ugly girl names: Fleur (sounds like bleurgh) Charlotte (sounds like a cross between churlish and harlot, and it's the plastic hat they wear in factories handling food) Florence (such an ungainly sounding word) Harriet (sounds like a Victorian spinster, though my ex neighbour Harri looked like a model) Evelyn (sounds like 'Evil Lynn' who was either a cartoon villain or should have been)
Names which sound like they mean something stupid in another language or sound like a trade name: Conor (I try), Timeo (I'm scared), Harper (sounds like Harpic the toilet cleaner, but also harpy, much worse)
Designer brand names like Kenzo (I know it's a real Japanese name, in Japan!) or Porsche (I'm not buying it as a variant of Portia)
Twee names like Poppy or Holly
Unisex names like Robyn or Rowan
Names I hate for no particularly obvious reason, like Louis, Lois, Amelie
Names which are not necessarily bad but belong to horrible people I used to know: Ronnie, Emma, Fiona, you are all a disgrace to your otherwise inoffensive names.
Right, I think I've managed to offend most people who have named a baby in the last couple of years...
