If you've mistakenly typed "kiljoe" instead of a correct word, here are a few possible suggestions. Perhaps you meant "kiln" which refers to a furnace or oven for baking or drying materials. Another option could be "killjoy", meaning someone who dampens the enjoyment of others. Lastly, "kilo" represents a unit of measurement. Double-check your intended word next time to avoid such misspellings.
