Here's why:
* "Noisy" is a two-syllable word ending in a "y" sound. Finding another two-syllable word ending in a similar "y" sound to rhyme with it is challenging.
* "Group" is a one-syllable word ending in a "p" sound. This makes it hard to find a rhyming word that also fits with the "noisy" part.
Possible alternatives to consider:
* Near rhymes: You could use words that have a similar sound but not a perfect rhyme, like "rowdy" or "crowdy."
* Descriptive words: You could use a different adjective that describes the group's loudness or behavior, like "boisterous, raucous, lively, animated, chaotic, unruly, or turbulent."
Ultimately, the best choice depends on the context and the desired effect.
