Nicknamey, puppyish, abrasively cutesy.
reminds me of "jewels" like as in "family jewels"
Also - Juuls.
I don't like
Miles or
James, either - the sounds of these names just grates on me for some reason.
the -s ending as a nickname ending seems synthetic, like calling a
William "Wills" or a
Katherine "Katz."
Feels similar to me, as when someone calls someone a nickname with -ster. Hey it's the Jule-ster!
As a French guyname - I guess it's somewhat fashionable in
France, but I've never heard anyone pronounce it as a French name where I live. So to me it's only a hypothetical, and it seems dated to me because I've only ever heard of
Jules Verne.
