Here are a couple of possibilities depending on what you meant:
* If you're looking for two words that rhyme with "stroobly" - there aren't any perfect rhymes in the English language. However, words like "gloomily" or "roomily" might be close enough.
* If you're looking for two words that sound like they could be part of the word "stroobly" - you might consider "strobe" and "slowly" or "strong" and "bloody".
