Wdyt of [name_f]Kiki[/name_f]? Most likely I would use it as a nickname.
It’s spunky and Cute, [name_f]IMO[/name_f]. It also reminds me of Bad Moms (the movie), as one of the main characters has this name.
As a nn, yes. What would be the formal? [name_f]Katherine[/name_f]? [name_f]Kaitlyn[/name_f]?
It’s a cute nickname! I also like Coco as a nickname:)
I like it. I call my son [name_u]Kit[/name_u] this from time to time 
[name_f]Kiki[/name_f] is really cute!
It makes me think of [name_f]Kiki[/name_f]'s Delivery Service.
I’d love to see it as a nickname for [name_f]Catherine[/name_f], [name_f]Cathleen[/name_f], [name_f]Caterina[/name_f], [name_f]Catalina[/name_f], [name_f]Carina[/name_f], [name_f]Calliope[/name_f], [name_f]Carolina[/name_f] etc
[name_f]Kiki[/name_f] is Kute!
My name is [name_f]Katherine[/name_f] ([name_f]Katie[/name_f] is my primary nickname) and I’ve been called [name_f]Kiki[/name_f] before. I think that [name_f]Kiki[/name_f] could work for any name that either starts with a K- or has a prominent k sound.
I think it’s cute, esp as a nickname. The first thing I think of is that drake song that goes “kiki do you love me” lol but it won’t be a lasting association.
