What can [name_m]Rush[/name_m] be a nickname for??
[name_m]Russell[/name_m] is my first thought!
[name_m]Rushford[/name_m], Rushmore, or [name_m]Rashawn[/name_m] also come to mind.
[name_m]Russell[/name_m] and [name_m]Russo[/name_m] is all I can think of! [name_u]Or[/name_u] maybe a name where it’s Ru___ Sh__ so like [name_u]Rudy[/name_u] [name_u]Shane[/name_u].
I like the suggestion of Russell!
These might be more stretchy (but Rush feels like Chip, Bud, Spike, Ace - could be quite generic/loosely tied to the name):
Roscoe
Shura (contains Rush, backwards?)
Azarius
Marius
Cyrus
Remus
Ramesh
Lawrence / Laurens
Lazarus
Rufus
Yeruslan / Ruslan
Fergus
