The phrase "bore company" implies a dull or uninteresting social gathering. To describe the opposite, one could use the antonyms of "bore" and "company." For instance, a "stimulating" or "engaging" group of people would be the opposite of a "boring" company. Similarly, if the "company" itself was varied and exciting, one could describe it as a "lively" or "diverse" gathering. By using these antonyms, we can paint a picture of a social event that is intriguing, entertaining, and memorable, rather than tedious and unremarkable.
