a) a social misfit, but someone who still somehow functions within their society.
b ) a person who doesn't follow professionally in the footsteps of either parent
dude 1) i can't understand why my parents don't appreciate me more. i want to a history teacher; my mom is a chemist, and dad is an engineer.
dude 2) did you lol ever consider that you might be a carrot in god's potato field, and that your parents wanted you to professionally follow in their footsteps. (starts laughing)
A carrotcruncher is a term used for a supporter of southampton football club, so called due to thier accent which sounds like a 17th century farm hand, in fact the vast majority still work on farms in the Hampshire and Dorset area.
