look up any word, like ratchet:
Some one providing support to a more skilled worker.

The term comes from the construction industry. A hod is a three sided box to carry materials to a mason. The less skilled worker carries material in a hod to the skilled worker.

Expanded to other jobs and professions "hod carrier" would be helping a more silled person complete a task.
I did not have an important role in the trial. I was a hod carrier for the trial attorneys.
