Theodore's nickname in Holes (both book and movie) is Armpit. Although in the movie, they make out that it is because he has bad armpit odour, it is actually because, while at Camp Green Lake Correctional Facility, he was bitten by a scorpian. He was actually bitten in the forearm, but the pain travelled up to his armpit. He started complaining about the pain in his armpit, and therefore he was nicknamed Armpit. This information was showcased in Louis Sachar's sequel to Holes: Small Steps. This story is intirely about Armpit, taking small steps to regain a usual life.
