Hey compadre breh!
I wonder if you're talking about the random spouting of facts (which I don't attribute to race, more of a person thing).
I don't think knowing and discussing trivial knowledge (when on topic or helping transition conversation along) are annoying.
But if someone is just spouting these trivial facts constantly without rhyme or reason?
Did you know rattling off rambunctious rhymes randomly without regard for reasoning can be a reason for rhyming?
