The word "all-fired" means extremely or intensely, and is often used in colloquial speech to emphasize a statement or feeling. Some antonyms for this word include "mildly," "moderately," "calmly," and "temperately." These words can be used to convey a more measured or subdued approach to a situation, rather than the fiery and passionate approach that "all-fired" implies. For example, instead of saying "I'm all-fired excited to go to the party," one could say "I'm mildly excited to go to the party." It's important to use language thoughtfully and intentionally to accurately express our emotions and intentions in any given situation.
