   extra snob appeal

late 18th century (originally dialect in the sense ‘cobbler’): of unknown origin; early senses conveyed a notion of ‘lower status or rank’, later denoting a person seeking to imitate those of superior social standing or wealth. Folk etymology connects the word with Latin sine nobilitate ‘without nobility’ but the first recorded sense has no connection with this.
