Can somebody explain that nickname “sama” - how is that supposed to be pronounced? If it’s “like Sam A.”, then that’s a terrible nickname. If it’s “like sam-uh”

Can somebody explain that nickname “sama” - how is that supposed to be pronounced? If it’s “like Sam A.”, then that’s a terrible nickname. If it’s “like sam-uh” - what gives? That’s not how Sam Altman sounds? I realize it’s a little absurd to be upset over a nickname but it somehow like really triggers me to see “sama” (lowercase, too!) so many times in one weekend.
