The name Forrest! What do you truly think?

My fiancee and I are having our 3rd child and well he wants to name the baby forrest if its a boy. Not to mention we have a son already named daniel though. I think of forrest gump and he won't listen neither will my mother! She said no one will no that movie by that time which is a lie! It is a classic. So I need advice. I might compromise and settle for benjamin Forrest. But what do I do? I am nervous about my children getting made fun of in school and everything.
