The names I like aren't so much guilty pleasures, pretty normal names really, Theodora (Teddie) for a girl, and the male equivalent Theodore (Teddy) for a boy.
I like names that are loaded with vowels that are hard to pronounce and hard to spell. I don't think my mother would ever learn to spell Eilidh or Ariadne or Isolde.
For boy's names my guilty pleasure would be stealing celebrity surnames. Daltrey, Tennant.
Bellatrix and Hectorwouldnt use them tho
I always wanted to call one of mine Bellamy after Matt Bellamy from muse. OH doesn't like it.
