I'm not exactly sure what the question we're discussing is here.
If it's something like "What are all the japanese sound symbols?". That's a non-answerable list question and should be closed.
If it's "What does 'gerogero' mean?" That's either a general reference question, or more appropriate on JLU. Note that JLU is not particularly welcoming of questions that could be answered with a search of any of the dictionaries listed in their Resources FAQ (for example on jisho).
