Aniki-Bóbó is akin to a children's counting rhyme that has existed in various forms since well before when?
Eeny, meeny, miny, moe "Eeny, meeny, miny, moe"—which can be spelled a number of ways—is a children's counting rhyme, used to select a person in games such as tag. It is one of a large group of similar rhymes in which the child who is pointed to by the chanter on the last syllable is either "chosen" or "counted out". The rhyme has existed in various forms since well before 1820, and is common in many languages with similar-sounding nonsense syllables.
Choriamb In Greek and Latin poetry, a choriamb is a metron (prosodic foot) consisting of four syllables in the pattern long-short-short-long (— —), that is, a trochee alternating with an iamb. Choriambs are one of the two basic metra that do not occur in spoken verse, as distinguished from true lyric or sung verse. The choriamb is sometimes regarded as the "nucleus" of Aeolic verse, because the pattern long-short-short-long pattern occurs, but to label this a "choriamb" is potentially misleading.
