Short for "grommet". Basically a young'un who is still learning to be rad. Not exclusive to surfing and skating, the term has been co-opted by most individual outdoor sports (skiing, snowboarding, kayaking, etc).
I saw this gromm ripping it up in the Alta Chutes the other day; kid might be legit rad soon...
