na-na na-na boo-boo

• na na na na boo boo
• (sung to the same tune) na-na na-na na-na, na na na na na na
• nanny nanny moo moo

Apparently from the longer childish playground taunt sung to a tune particular to the taunt:

I'm better than you,

na-na, na-na, boo-boo,

stick your head in doo-doo.

Na-na and boo-boo may be imitations of sounds a baby or young toddler might make. Boo-boo may also indicate boo-boo, a minor injury which leaves a mark on a child such as a scraped knee.

     [Translator's note by David R. Slavitt] ...here is to make clear that this is a display of Schadenfreude, an elegant cocking of the snooks, a protracted "Na-na, na-na, boo-boo," a symphonic Bronx cheer!
