What is a "Rookie" exactly?

As you can see from the description line on this blog, I will refer to myself as a "Rookie Ashtangi".

I found a definition of "rookie" whilst wasting my time away online. Don't even ask how I wound up on the "Digimon forever" website:

Rookie:

"A stage in a Digimon's life when it learns a unique attack. It uses the Digivice to digivolve to this stage. This Digimon is usually exceptionally strong".

Can we make that:

"A stage in a person's life when it learns a unique approach. It uses the Asnavice to ashtangivolve to this stage. This person is usually exceptionally strong".
