The phrase "chomp at the bit" is an idiom that describes someone who is eager and impatient to do something, often in a way that is uncontrollable or excessive. Antonyms for this phrase include apathy, indifference, and patience. When someone is apathetic, they lack interest or emotion towards something, and when they are indifferent, they feel little concern or preference for it. Patience suggests a willingness to wait and an ability to tolerate delays or setbacks without becoming anxious or frustrated. Instead of chomping at the bit, one can approach a situation with a measured and calm demeanor, showing restraint and thoughtfulness in their actions.
