I like [name_u]Wiley[/name_u]! I have a friend that nearly nn’d her [name_m]William[/name_m] “[name_u]Wiley[/name_u]”, but I like it on its own too. I call 99% of people something like “love” or “lovely” or “buddy”, plus refer to my brother exclusively as [name_m]Buddy[/name_m], though his given name is J0hn, so [name_m]Buddy[/name_m] as a full name does seem a bit odd to me but I like its sound in general.
I think [name_u]Flip[/name_u] is SO fun, but would personally only use it as a nn for [name_m]Philip[/name_m].
I also love [name_u]Bo[/name_u], [name_m]Boomer[/name_m] (idk why I love this so much, but anyways lol), [name_m]Mac[/name_m], [name_m]Baxter[/name_m], [name_u]Royal[/name_u] (ROYAL!), and [name_u]Duke[/name_u], too.
