Na Na Na Boo Boo is an alternate version of Na Na Na Na... It’s another verbal version of “In Your Face”.... Most commonly uttered by preschoolers up to and including the third grade. Spoken in a Sing-Songy tone..
When Oliver got spanked for jumping on the bed, Jaden taunted him singing “Na Na Na Boo Boo... You got a span-king!”...
