I forgot password
but I know the idea

let say password is "stupid me forgot bitcoin password 6 9"

with spaces

I know for sure that 6 9 always at the end or not at all
I know it might be 69 or 6 9
I know I might not use spaces at all
also I know that "stupid" always comes first or "stupid" sometimes might be"retarded"

how to make this structure?
how to make sure that specific possible words are coming first or last?
