I know a very adorable little boy called Bailey, who loves golf and lego. His parents are not chavs at all, as in they both have jobs (dad is a plumber, mums a secretary), and a mortgage, but the parents do have slightly chavtastic taste in their tattoos and clothes etc. They have commented that their taste in names - they love the boys names Harvey and Bailey are considered by some as chavvy.
I dont think it is a chavtastic name, but for me, it is a dogs name (I used to have a dog called Bailey). I find other names more chavvy, if you love it, go for it.
To me chavtastic boys names are the really silly ones like - Brooklyn, Junior, Billy-Rae, Billy-Jay, Chayse, Cruz.
