One's not into fancy elitist names (6)
I believe the answer is:
titles
'names' is the definition.
(titling is a kind of naming)

(Other definitions for titles that I've seen before include "Mr and Mrs, say" , "Names of works of art or literary compositions" , "Terms" , "Lord, Lady etc." , "Names of books or lords" .)
