What does игрь mean in Russian?

Игрь can be used as a name. I saw it on a Russian website.

If it is lowercase, I checked online and found that it actually means growth regulator, so the first letter of the name must be capitalized. ;)

p.s. The netizen above said that Игорь is the name of Игрь. I can’t confirm it, but I think it’s good.

There is also a similar word Егор commonly used in Russian jokes, which is equivalent to "Zhang San"
