As the title suggests, I’m wondering what you’d nn someone named [name_m]Ulysses[/name_m]? What I’ve thought of so far is Ulyss…
Also, do you like the name [name_m]Ulysses[/name_m]?
It’s an interesting choice. I like it
Some nicknames could be:
Uly
[name_u]Si[/name_u]
[name_m]Sy[/name_m]
I would use Uly
I like U-[name_u]Lee[/name_u]. [name_m]Just[/name_m] [name_u]Lee[/name_u] could also work.
I knew one. We called him “Big U”. He was really buff, though, not sure how it’d fit a tyke. 
Although, come to think of it, Big U was definitely a [name_m]Little[/name_m] U at some point…
