I'd say my least favorite trends are "modern" word names (Like
Happy, Cruise,
Jet, Cove,
River, Cloud,
Storm,
Dream, Bolt, Brewer, Racer,
Legend), traditionally male names on girls (that don't have much history as a female name. Something like
James on a girl isn't for me, whereas
Joyce is beautiful, and I can't see it as male), and the "-son" and "-ton" endings.
