It's just a small Japanese poem that consists of 3 lines, typically laid out as 5 syllables, 7 syllables, 5 syllables (at least the English version is). Unfortunately haikubot didn't see my haiku I made about haikus. :(
It doesn't mean anything other than a bot noticed a pattern. Kinda like you noticing when someone accidentally says a rhyme.
Thanks a lot for your explanation!
I think it took me like 5 times asking and 1 month of time to find out. Although I didn't use Google.
